At some point today, probably while working on that metal cylinder, I was convinced that I would never finish this thing. But finished it is and relieved I am. One of my possible ideas for Week 5 was just a setting/background study but after this thing you can forget that. I'll do something more relaxing and save the environment study for later.
So even though it did take me a whole week to do, it's a relief to be finished before Wednesday because I have a day to relax and decide what to do next.
This actually turned out nicely and I'm considering selling art prints of it.
