This is great. I love the woman's expression in the latest one, like, 'how the heck did I get up here?!' Your grey scale & line work is enviable.
As a first timer to CG, I'm on a pretty steep learning curve. I've got a lot of work to do. With my horrid lack of self assuradness, it's taking a long time. Hopefully I'll have something not crappy to present at the end of February!
