Brittle Hollow! I'm doing most of these locations in the order that I visited them in game, so this was the third planet I went to. I find it really interesting to see how different people play the game. I made sure I found everything on each planet before moving onto the next one, whereas my friend just went wherever he felt each loop.
I had to experiment with a bunch of different techniques for this one, and I'm pretty happy with how they turned out. I feel like committing to doing a series of artworks is how I improve the most at art.
