Absolute beginner here. Drew Picasso's Igor Stravinsky upside down. Haven't drawn in years, and even when I used to draw I was really bad at it (I was just a 12 year old drawing medabots).
This is how it turned out:

I think it turned out ok, though there are some proportion issues. I noticed it halfway through and it was mostly because of how I started (and also because I always sucked at drawing proportionately), but I didn't want to start over so I did a few things like drawing the guy's right wrist.
