Great going.It's a good thing you've put effort into it. However there's still a LOT of room for improvement, for eg. the left hand seems kinda off,cos since its going into the pocket, the elbow would go farther from the observer and the wrist then starts coming towrds the observer, so you wanna add that forshortening.

Also the shading could do with some work, this way it just look like a rough sketch.You need to refine and eerase where it goes out the outline.

Keep at it :)
