I think.. I THINK, I got most of this drawing's proportions well, I still have problems with the light source, but I think it looks decent enough to deserve a bit of CnC



This is a friend's character from an RP on the forums, credits to him for the color and clothes choice.

Well I can tell you right off the bat that you didn't get the proportions right at all, and it doesn't help that you chose the worst possible pose for someone wearing those types of clothes, everything just looks awkward
Besides th he proportional issues, which will go away with practice and study, you seriously need to work on lighting(which you know about,) color usage(because everything looks pretty bland and boring,) clothing folds and hands
The clothes thing might be the biggest issue though, your folds are just all over the place and make no sense. They have no flow, that's ddfinitely something you're going to need to study up on
I look forward to seeing better work from you in the future

Well, crap.... I mean, I have no idea how exactly does the clothe folds in that position, I don't have a coat or pants like that to even see it irl, sp I just draw it and try to make it look good. I don't see any tutorials on how to draw clothes or something like that so, could you tell me how it should have looked exactly?.

And in which part I messed up the body proportions.

Study Anatomy and for clothes, Study Drapery.
Work on Poses. I would say just sketch light figures in different poses.

Proportions -
The Guns are HUGE and his head is too small compared to his body.

Da guns. Da shining guns. * o *

Why so big though? :I
