It took about thirty hours, but it's finally finished! Huzzah! Obviously, I'm a sucker for detail, and it's really slowing me down. This is the sort of thing that can be achieved by someone with minimal artistic flare, but who is incredibly anal retentive and has gratuitous amounts of spare time. I think it's high time I learned how to speed paint. Despite all this, I'm happy with the end result, so I can finally get back to my uni work!
