I applaud you for drawing a frontal picture in motion rather than static. Nice pencil work and it seems ok anatomically. All I would suggest is that I would expect his right pectoral would be higher or more taut than his left as his trailing arm would bring it up slightly and tighten it. Good work .

Anatomically it's nice, but the face...hmm...kinda looks like he's sick. I didn't mean to offend you with that, I know it might have been a bad comparison, but that's how I feel about it.
Open those eyes, and try to match the shape of both sides as much as you can, making them ALMOST simetric. I'm saying this because his left cheekbone seems to be a lil higher than the right one.

Overall, it's a good piece, although I think you can spend some more time on it correcting these mistakes. Keep it up

Nice drawing Jane
but im not sure about his right hand...it seems odd to me...it looks like hes hiding something..and that left hand...well..study foreshortning..its tough i know..but u can do it u could make his shoulders more wider, and pay attention on ur lines too, speically the lines on his left leg, i think u should listen silent music while drawing just kidding
....anyways just keep working,

nice character +10/10

you know it isnt bad.

have you checked out loomis or forster's books.

might want to try brushing up on 1/6th, 1/7th and 1/8th principle.

Beautiful linework! I love this sephia tone and the texture in the paper as well. Makes me wanna run and draw! O_o

Try looking at your sketch in a mirror, it'll reveal stuff that is off. Nice pencil work and character.
