Sonic Adventure, Human version

Hi everyone!
I really wanted to do a Sonic fanart, because I love it and it has been my favorite videogame & my favourite character in my childhood.   I remember me drawing all the character every single day wen I was 10 or 11. 
I don't really like how it came out but yeah, here it is. I started coloring it but I realized that maybe it was batter just with the lineart (or maybe I'm too lazy to color it LOL).
I hope you like it and sorry for my bad english
