I'm not happy with this AT ALL but I've spent so long doing that I had to post it. The shaded bits look too dark, I haven't captured the shape properly and I generally hate this drawing. But I'm glad I finished it. It means I can leave it and begin something else. If I had just left it, it would have always been there, waiting to be finished - niggling away at me. But it's done. And I can rest.
**Edited on 29th April. I actually quite like it now. Perhaps it's all the positive feedback (which I'd miss out on if I didn't have a blog!). In answer to your questions, this was done with a black ballpoint pen.
