Do you have experience animating as well? We probably need some character and enemy animations and so on. I'm also not sure if your art style would be the best. It's a bit too simple and playful. Do you have something a bit more polished?
(Oof its a little I'm sorry but we already found someone who will do the pixel art for us.
Your pixel character is not bad for someone starting out. But I don't think you can do animations and all the other more complex art that we probably need.
I wish you good luck with your art! Keep at it and I'm sure you can get somewhere.
