...at last! I'm quite pleased with the end result. After close on 30 hours work it's just as well. Today I spent a couple of hours finishing off the bottom right corner then going over the entire drawing, refining and darkening some of the shadow side and generally tidying it up. I still wish I had made more effort to get the whiskers a bit brighter but it's the best I could do. A slightly wider indentation was required....I'll remember next time.
