Wow you sound like exactly what my dev team is looking for right now!
If you're still looking for a project, our game is a 16-bit horror-leaning game with some cozy and humorous elements to it! It takes place in a forest, and visually-speaking we're going for something pretty similar to the examples you provided from your portfolio.
I'm an artist/animator, but now that I'm the project manager, we could really use some help with getting the items/props and environments/backgrounds done.
You'll be working with me and one other artist, so you won't have to worry about tile sets either!
