I'd say the top one, really great colours. It also looks like it blends more wiht the background than the second, especially around the arm. Good job.
First version looks nice. Just maybe his hairs are a little overlightened, apart from that, good lighting, good flow. I am just not a real friend of the text you used.
First is better, cause the other has some wrong details. I really dont like ur tipograph.. :X But the result looks nice
