If you haven't seen it yet,  Venigsun has started a forum for teaching realism, specifically "furrealism" in her style. Lesson #1 has been posted and as you can see, I've given a go at it.

The lesson was to show your skill so far and complete the other half of the drawing. I'm not quite so adept at drawing without outlines, and if I removed them, it looked really awful. So, I just left them for the meantime. Anyway, here's my attempt at furrealism, without any insturction so far...

If you are interested, the forum can be found at the link below.
