Nice guiar playing!
cold, strong character like these are the coolest! ^^
The expression is very good. The legs seem a bit on the skinny side, but the rest of her is proportional. The guitar seems oblong, and uneven. The background seems a bit off,like she's specially posing for a picture.
ahh she so cool!
Ah, this is just so cute and cool!
I agree with the comment below- leaving the character colourless really suits the patterns and colour of the background, and gives the picture a nice effect.
I like that you added those words and characters behind the characters too! ( :
This is just great! I am actually glad that you didn't color the character because it gives it more of a manga feel.
