I am new to pixel art, I started this year, but I am looking to push myself. I haven't done much tiles, but I'm not afraid to give things a try. At my skill level, I can do basic idle sprites, but for more advanced things such as running sprites and things of the sort, I may not be the guy yet. I am constantly improving though. There will be a link to what I've done so far, if it is something you thing would be good for you, hit me up either here or via discord. I'd be more than happy to help.
