Well, tbh I'm not a fan of how you made the Bojan sig, but it's a good and creative idea.
Firstly: He is not blended in, not even a bit, looks a bit crazy.
Secondly: The render effecys are bad and make him look terribly LQ. Try duplicating the render layer and use different layer stiles; color dodge, color and such. Then play around with the opacity.
And I really think you should check some tutorials out, not use them, just to learn some basic skills you know

Keep up the great work though, looking forward to seeing more!
And if you post your sigs in different posts you are able to get rep for each one
