I think that you have been looking at it for so long, it's starting to bug you. It looks very well-done and professional. After looking at it for a while, though, I think maybe the lush-ness of the environments almost detracts from the players.
The tiles almost seem like they would be found in a GBA-version of Super Mario RPG. They are very rich and saturated, however the players have more of a realistic drive, rather than a brightly coloured, comical character. If you take a look through some of the tiles in Final Fantasy Tactics, (example below) you'll see that while the envireonment is 3d-rendered, it is still less detailed than the characters (along with a much different palette), and in turn, it makes the players stand out.

(i realize that this is a poor-quality screencap, but it gets the point across.)
Trust me, this really pains me to say, because the environments are
amazing. But I think it's something you should consider.
