As the picture says, please don't hold back on criticism.
added a regular form of him. The Regular form might be his real form. I increased the height.

Very nice :) reminds me of Nightmare (Soul Caliber) and Chad (Bleach). It's very easy to read.

Haha, thank you. I'm glad it's to your likings. D

Your welcome :)
The second version is a little too thin along the waist, however if you were to make other characters in a similiar fashion you may be able to pull it off in a game or series. Other than that I'm a little thrown off by the left shoulder, it's a bit blocky; the left leg is also very flat along the inside but that could be fixed by widening the waist. I've also noticed that the shading on the left foot is a bit contrasting especially compared to the right foot and the pant leg extends a bit too far down. Expanding the height on the character was a good idea though :D

Alright, thanks for the criticism for spotting out my mistakes, I'm going to fix this right away.

I'll be readding my sprites as soon as I finish up some sprites.

the banners are unnecessary and annoying

sprites are cool though

That's in your personal opinion. I've done this in all my forums mostly phantom g's and club syndicate. It's a common thing everybody does it. Also leaves out a little more bold, since people tend to ignore messages, and go straight for the pictures. Anyway, thanks for the compliment.

Even though if you want to get just feedback on just the sprites then the best thing might be to leave ' em out, outside of Phatom G's and etc., because they are very distracting and so forth; they take up more space then the sprites you're showcasing.

But up to you, your party.

I thought it was a neat idea :P
Depends on the person I guess
