It looks pretty awesome, but it seems like you were relying on those C4D's too much, unless of course, you made them.
The lighting is a tad forced, next time i suggest trying to make it look more natrual, instead of just brushing. The effect's are pretty cool, they go well with him, however as 'Wizard' said, it look's like you were relying on the C4D's a little too much. The composition isn't bad, like i said, the effect's go well with him, however like i also said, it look's like you were relying on the C4D's a bit too much. The depth is pretty straight, so your good there, i think it was your use of C4D's in the background.
