I like it, 7/10.
But, the yellow on his face seems a little out of place, looks like a weird greenish over the blue. The text is alright, I personally don't like side texts, but with the way you made the sig, it looks good^^ Also try to add a "focal"
Like a bright spot kind of, the main focus of the sig. Add a little more stuff around his hand, or something.
I like the blending/background.
Nice work
