I like the style that you've drawn this cave in and I'm very fond of the color choices. The minty and the verdant green complement the muted purple-red in the background, and together they create this juxtaposition of mossy and lava-y atmosphere. There is an appealing "organic but grid-y" aesthetic which you've achieved with this cave that is genuiely cool to look at. It gives off the vibes of the background in an early Apple II graphic parser adventure. I can tell there was a lot of thought and work was put into this. I get the impression this would be a level with some platforming mechanics, particularly given the cylinder shapes at the bottom. I would gladly play a level that looked like this in an old platformer. Thanks so much for sharing!
