Lmao, great expression. I'd darken the background to show more of the dude. Other than that its nice.
Your lack of knowledge on the subject makes you look dumb. Theres a background and a foreground. The foreground should actually stick out a lot more. Theres no clear focal point in signature. edit: Simply, make him "pop" out more.
Lol yes, thanks for explaining obvious things to me in order to make yourself feel smart. I still disagree with your suggestion, despite your newfound self-assurance.
