Hi, everyone! I'm back at my hometown for a while, so I there's some time for drawing. Again, found no pencils at all. So here's another ball pen drawing. Done in a day. No shading on this one, because I wanted to keep it as clean as possible. Making the lines with a ball pen is a pain, because no mistakes are allowed, but I'm pleased with the final result. Enough talking, here it is:

First, figuring out where the parts should be:

Second, darkening the lines and adding the rims:

Third, filling some of the parts that should be filled:
