Resident Evil 6 Japanese School - Jake x Sherry

This is a sketch I did some time ago. I decided to color it 'cause I wanted to try a new brush on Manga Studio 5, a copic brush.
I don't know, I'm not really satisfied. I tried to color like some manga's covers but it's really difficult.

This time I drew Jake and Sherry in a japanese school, with japanese uniform. I read a lot of shojo manga so I really wanted to see them wearing this clothes.

Obviously the background isn't mine (unfortunately), I took it from Manga Studio 5.
