hi!! i really like the art!! my overall suggestion is go over your dark spots with an overlay layer just to really make those dark parts dark! In contrast, however you like to do lighting, really make the light pop by making it brighter!!

if you need me to demonstrate what im talking about its no trouble just lemme know

I like the art but shadows in front view look strange tbh
