woah woah WOAH!!! 170 COLORS!? Pixel art is about limiting your palette, and most of the colors that you use only appear in a miniscule part of the overall piece, so small that we can't notice. Time to do some cleaning up! I like your iso style, though! Keep it up and don't leave something halfway done.
unfortunately I learned the coloring rules after I made the art. Thanks for feedback by the way, I am going to clean my faults.
