My Drawings/My OC's

Basically It's a book of my Drawings and my OC's (A.K.A Original Characters)...I don't consider myself as the best drawer in the world...I just like Drawing...This'll be like a doodle book for me or like a portfolio of my characters. No matter How good or bad I am...I accept criticism. Negative nor Positive! You know what they say ...
Haters = Motivators
Just tell me what I'm doing wrong...And I'll improve it!
