sketch was done by a mate i inked+ edited etc. rate/hate first large piece of mine found it pretty fun
It's nice but the execution could be better, I think you should get rid of that weird lighting overall and just go for a plain paper texture or something as the background.
It's really cool, the only problem is that the lighting doesn't interact with the drawing at all, which makes it look like it's in front. Also, the bright light behind the drawing really makes it look pixelized, you should apply a slight gaussian blur to the top half of it.
Decent concept, terrible execution and the realism is bad as well seems like not much effort was put into this, lighting is random and effects are scattered. Keep trying stuff
