Comic Panel Practice

I've been trying out some new brush settings on SAI lately. I'm still debating whether or not my graphic novels are going to be in color or black and white. I would love for them to be in color in all honesty but at the same time I really like how black and white comics/manga look. I'm sure i'll figure it out eventually.

Oh, and I guess I mention that this is Catherine's new design. I decided she's going to be a rabbit instead of a fox lol
