Kokonoe Blazblue

Here it is!
Kokonoe, I decided to draw it with my friend a month ago, so we have done a quick sketch for our contest... So them i decided to make one with i little more work.

I'm enjoying my process to make drawings and stuff, paint. But I think the face of the characters are being very simple, do you think that? Do you think it needs a little more work?

Thank you
