Hey, thanks! Your sci-fi work sounds really cool too.
For my pixel art workflow, I mainly use Aseprite. It’s probably the closest thing I’d recommend if you’re looking for a dedicated pixel art tool. I use it for drawing/editing, pixel cleanup, color adjustments, separating sprites, creating sprite sheets, and animations.
Aseprite is pretty easy to get into, especially if you’re already comfortable with something simple like Paint, but it has a lot more features specifically made for pixel art and animation. :)
