Too late for the deadline but still wanted to share

This was fun! Yet I think I was going for too much detail or accuracy instead of exploring the lines.

For me the elipses are not the hard part, but putting down pressure at the right time is. When I try to adjust my pressure THEN I mess up the elipses. Any tips?

Im drawing digitally but forced myself to not always zoom in to have an easier time with small ellipses. Really fun exercise.

My take on both levels. I found it very difficult to keep thinking three dimensional while drawing the shapes and I somehow ended with some shapes curved instead of with straight lines. First time doing this but I already think I learned a lot.
