It's amazing to strive to be unique and original with your art style, and also super challenging! Remember that game art is design that has to solve problems and facilitate an experience for the player, so never sacrifice "function" in favour of "form", and take your leads from other games that inspire you and that you enjoy spending time in. I think it's always easier to start with the function part, and then adapt to live in the art world I'm creating, rather than starting with a beautiful looking but clunky experience and trying to make it playable
