Congrats on your first pixel art jam!
Your scene looks nice! I really like the vignette effect you added in the corners, it really draws attention to the middle of the screen 👌
If you want to turn this into a game, maybe you will need to make the character a bit thicker. Right now it reads well but I'm not sure it would still read as well in movement. Either way, I wish you luck if you decide to make the scene interactive!
