Shading Practice - ACEO

The other day I whipped out a pack ATC sized Bristol board a friend had given to me and decided to do a little shading practice. Its been awhile since I've worked on art, so I'm trying to get my art muscles all nice and loosened up.

She's pretty much a replica of the girl in my previous post. Just wanted to get some tonal values down to see how I want to progress with her on a larger scale. I was pretty pleased with how she came out despite being out of practice. Maybe I'll make her available as an ACEO after I finish the painting.
