When looking for inspiration for a game you can look to real life experiences which will likely result in a vision and take unique to you, or to other media which will be slightly less original, or games which will be derivative, or games based on other games based on other games etc which will result in schizophrenic feeling fictional universes etc
On a smaller scale when trying to make a tree asset, you can personally try to create a tree sprite or model based on real trees you personally observed, or on ways other artists have already interpreted trees in art and cartoons, or on ways game artists have already created tree assets, and the deeper down you go the more of a caricature the tree becomes
