6/10, the dark edges are a little too big, almost overpowering the sig. Also, I think there's a lack of effects around the render, try to make it blend more in certain places and make the hand and face stand out more. I would try to achieve this by blurring the left arm and body, then sharpen the face and right forearm.
That is one big signature lol. I suppose mine is small though. Either way, your background is a little boring, but that might be more practical in this situation since you're trying to convey information. I do like the layout, it's almost like an advertisement lol. I'd give it an 8/10.
