Hey! Your work looks really interesting, and I think your pixel art could fit the project I'm working on.
I'm making a small top-down zombie game that's already playable. I'm handling the programming and gameplay, and I'm currently looking for a pixel artist to help shape the game's visual identity, especially environments, characters, zombies and animations.
Since you're looking for a small project to build your portfolio, I thought this might be a good fit. It's a hobby collaboration with no upfront payment. If the game is eventually released commercially and generates revenue, we'd agree beforehand on a percentage of the revenue for the people contributing to the project.
If you're interested, I'd be happy to show you the current build and tell you more about it :)
