Your sprites excel in humility and simpleness, which I find an interesting approach. However, I do think you should be a bit more ambitious and attempt more ... complex designs. Until now you have limited yourself to adding like one or two parts max, and then recoloring. The result is fine, but I don't think I could remain entertained with much more of this. You definitely have the technical skills as I don't really see any evident flaws on any of these.
To sum it up, you made your point. You like cosplay-trainers with a hat of the pokémon they're representing. Time to surprise us with something else now
