Ooooh! Colour would look awesome!
You attention to detail is awesome, and hooray for perspective!
I think I see what's wrong...
His shoulder (the one we can see) is a little too big. If you measure the length of his head from top to bottom and then measure from the middle of his chest to the end of his shoulder, it should stop where that first fold is.
Also, The sphere confuses me, is it behind his hand or behind his shoulder? It sort of starts off behind his hand then manages to finish behind his shoulder...
I can do a red-line for you if that would help you!
I hope you understand what I mean and aren't taking it the wrong way!
Critiques help artists learn from their mistakes, and I know from experience that some people can pick out the mistake easily, when you know there's something wrong but can't quite say what it is. I personally love getting critiques because then I can keep the pointers in mind for my next piece of art!
Sorry if You didn't want a crit, but I thought you might appreciate it as much as I would!
I'd love to see it coloured!
