My suggestions:
-Lloyd resprite
-Resprites and improved visual effects for Naruto and Ichigo's final forms to bring them up to date with their new looks
-Touch-ups to Phase 8's Lava
-Wall clinging (not jumping, clinging) for certain characters like Sheik (can do it in Brawl) and Naruto (uses chakra in the anime to stick to surfaces)

And I've got this gut feeling this one will be rejected but:
-Can we get some asymmetrical sprites for Link, Lloyd, and Samus? It just bugs me when I see them switching hands all the time (and Samus shouldn't even be capable of switching, her weapon's position is kinda locked in place).

At the moment, I don't think they'll worry about "flipping the model" right now, as that would require those characters sprites to double in amount just to add the different directions for those characters. I think they might do it at some point but not as of now, as the devs seem to want to add more content that isn't just aesthetics.

Yeah, I kinda figured. Still, it would be nice to have them.

Oh, and I remembered another suggestion I had. You know how you can prevent certain stages from being selected when playing on random stages? How about we do that for characters? (Example: You're fine with playing against any random character, so long as it's not Peach or Jigglypuff. So you turn them off under the options and now you'll never see them again when playing against random characters).

I actually posted this in the character speculation topic, but anyways.....

Here's a list of changes that might be good for Lloyd:

-His down special should be changed to guardian and should protect and do reflect damage.
-Move grave blade to down smash and sword rain to side special.
-Tempest should have short-midrange homing/aiming(increasing range if held). If it hits it continues downward and if it doesn't than the move cancels. This would boost Lloyd's recovery by using tempest to home in close to the stage, using tiger blade then quickly using tempest again.

Here's two reference videos:

And again it would be much better to just give him variations to his Sword Rain instead of changing Grave Blade because he would have 3 options when using Sword Rain. This itself would improve his combo ability since imagine if he could change up the last hit of Sword Rain into an air attack where he could then begin fighting in the air which is known as Sword Rain Alpha, or a version where he pushes them to the side and gains spacing which could probably be followed up in Demon Fang.

I'm saying this because Guardian isn't really something that would be necessary at all due to how it works unless you would want it to work similar to Fox's shine which you may as well just give him a new attack then.

Some changes to Yoshi (an already amazing character as TSON insists):
_When Yoshi goes to do his DJ, there is a brief period of his jumping animation that he flutters down, and sometime he hits the ground but still makes his classic "HMMMMMMMMM" sound effect. I suggest that if he touches the ground during this, Yoshi wavedashes instead of awkwardly landing on the ground doing nothing when the player expected to fly up. The alternative to this would be to not have him lose any height so that he never awkwardly lands.
_Have his DJ change his momentum based on his direction. If Yoshi dashdances, he can jump away from someone (they whiff) and then Yoshi DJ towards them (momentum instantly changes) and allows him to get a great punish. This would be the way his DJ works in Melee, actually. Currently it takes him a moment to change his momentum.

My Second Suggestion
After You Clear Classic Mode Instead Of Congrulation Screen With Only One Character It Will Show A Character Group
Instead With Which Series Is Character Example Mario Luigi And Peach But This Is Another Sometime It Not By Series
It Special For Some Character Example
Dark Team - Bowser Ganondorf Wolf Shadow
Square Enix Team - Crono Black Mage Sora Cloud Strife
Shonen Jump Team - Ichigo Naruto Luffy Goku
However If A Character Is Not Unlockable Example If You Not Has Not Unlock Luigi Yet It Will Show Mario And Peach Instead

...or you can just have your character's trophy fall down onto a MC theme backdrop, like the official games do.

Yeah I just see Lloyd as a combo heavy character. I don't think your idea is bad, its just Lloyd in my opinion shouldn't combo heavy.

What about about the other ideas I had? Constructive criticism is always welcome.

Ok, quick suggestion that I believe would help CPU's a lot. Make Bomberman's bombs that are still on stage when he's been KO'd disappear. At least in stock matches. When his bombs are on the stage, the AI for CPUs don't concentrate and feel like they can detonate at any time, so they air dodge a lot in midair. Kinda annoying.

In Some Fighting Game There A Maybe Semi Final Stage As A Rival Stage
Instead Of Free For All You Will Fight Your Villain Of The Series Or Rival Instead Example
Mario Vs Bowser
Link Vs Ganondorf
Sonic Vs Shadow
However If Some Character Of Series Dont Have Villain Of The Series Instead It Will Be Like Playstation All Stars
Example
Llyod Vs Ichigo
Naruto Vs Goku
Lucario Vs Mewtwo
After You Defeat Them You Will Hear Master Hand Laugh Then It Will Send You To Master Hand Fight

Guardian was Lloyd's down special for five years, from v0.1a up until v0.7. It was changed to Grave Blade in v0.8a because it just didn't work with his playstyle and was therefore his least useful move.

I think there should be more crowd sound effects during battles. The only time you can really hear them is when you select your stage, or when the crowd gasps as a character barely makes it back to the stage.

Let's hear some more cheering!

Yeah, you could easily find ten or twelve random people to chant character names, for example.

i wouldnt mind it, best to hear the fans of the game chant than use what brawl gots

i also wouldnt mind something more in the records section of the data menu. like a record of KO's made and other things. just start out small, nothing huge like time played last game and total time of gameplay...things like that
