Beautiful work, it looks almost as though it were painted!!!
Btw: Why is it that you've chosen to have characters decorated in various shades of the same hue?
Thank you! Regarding sprite colors, I tried to follow the old school gbc games! Some of them (bosses and bigger sprites) have one more color hue to make them look richer (so they're actually black, highlight and two hues). I wanted to keep the characters quite simple and contrasted in order to make them pop a lot more withing the environment, but I also have a few more options in store... :'P
