Umm...
Shouldn't the eyebrow on the right make that little circle?
Otherwise, nice work.

Edit:

Better?

Yes.
Better.

Everything in the face feels really squished together.

Something about his left eyebrow looks off... Can't quite explain what, though.
damn it

is that...Harrison ford?

Alright, thanks for the input everyone. For my next piece (of crap), I'll be sure to study up on some facial anatomy and eat lots of pickles.
You were joking about the Harrison Ford thing, right?

no.

It kinda looks like him, but whatever.

Latest stuff.

Sketch for my next piece. I'll be uploading new images of it in each phase.
Ignore the fact that he has no feet. Ran out of room on the page. I'll fix it later.

It's... not completely s***. For one, the proportions are in order. That's the biggest thing. Second, the perspective seems to be good, but I haven't seen too many of your drawings, therefore I'll refrain from drawing conclusions just yet.

I'd like to see your hands, now. No really, draw hands. If you can do this, you're ok. If not, then get to it.

But hands are fuggin hard, bro.

Shrunken down to a workable size. Next step, coloring.

Nice job, but where are his shoes?

His right thigh is a bit off, less concave on the outside would look better. The folds in his jacket are a little unnatural as well but that all changes with shading so there isn't much you can do yet. Other than that it's a good transition from paper to pixel.

Edit: A second look and I noticed the left arm is a little bigger than it should be, the angle of the rest of the picture also implies his arm would be angled *a bit higher *up not down. Fixing the angle should also fix the length.
