Well, I am very new to pixel art but I have looked at the forum for awhile. Today I thought I should probably start something so I begain a tileset. It is not that great but it is getting somewhere.
I've done small edits on sprites and stuff, but I am not good at picking colors.

I used very basic patterns and the colors aren't that geat. I tried other designs on the grass but I just couldn't get it to look that good. Any advice is greatly appriciated, anything will help my start at pixeling.
