I just discovered Karen Jurick's blog www.differentstrokesfromdifferentfolks.blogspot.com/, where loads of people try out a weekly painting challenge then post to the blog. This challenge was to draw from a photo upside down, then post the result right side up. Not too happy with my first attempt, but it was fun. Her head may be too small for her body, but her right ankle is nice ;-). There's some great work on the blog, and Karen's writing and challenges are interesting.
