Im not sure if ive said this before but your style is super unique! Especially the way you draw your eyes, it's pretty dang cool tbh. I think your traditional art actually turns out much prettier and easier on the eyes rather than digitally drawn art, and smoother lines too. Very nice!
Personally I don't really watch Steven Universe (the amazing world of gumball is more my cup of tea) but those gemstones look gorgeous! I thought that amethyst was a main character though? And rose quarts was the lion?
