This is an okay sig, while the render and text okay, the main problem with this sig would probably be that it doesn't blend as well with each other. The soda in the hand doesn't really give it much either with how it's just slapped in there. I see what you were trying with the smoke effect though, it's a good idea but it kinda hit the floor with the execution of it. While there are some faults, I won't go as far as to say this is a bad sig, but more a sig that has potential and could be improved on with a few changes.
