These are really cool. I like how you use tape to create some lines on some of those (at least from what I can tell). The colors, I would describe them as muffled, greyish, kinda muddy. Which is a good thing, as it adds up to the atmosphere. When you try to do more colorful stuff, its also really cool, as some of those "muddy" colors transfer over and give these a sense of unease. You should expand on that, work on some other bright colors apart from orange, perhaps some hot pink or even green.
