This is a really fascinating picture. I think it's because it's just so vague. I really have no idea what's going on. It's great to see a clear sign of you using acrylic painting. You seem to have gotten the perspectives done wonderfully. I just love the colors.
I can see all the little pen marks on this. I've just used those a lot in my life. It looks like this thing is trying to form a heart. The red tubes look like heart valves. The curves are done great too.
