I kinda wanna watch K-On, but I am scared it's gonna be to Seinen like Kill la Kill. Japanese storyline is incredible, but some how, they always find a way to throw in panties, or breasts, that just so happen to be big.
Great artwork, love the shading, which I can't do yet, and the guitar's awesome. Next time, you could make a better background, but it's fine as it is.
