It looks weird, please give female trainers their own back sprite instead of using the male one.
On top of that I'd want to ask for some kind of rework on the player character sprites in general, new hairstyles, more vanity items like clothes based on trainer classes or protagonists, more colors, maybe updating the overworld sprites to be based on BW.
I get that this is probably not a high priority but I personally would enjoy the game a whole lot more if we had more and better customization options for our player character.
