Make the hedges have a tinge of blue or purple? dunno, just seems like a ****load of green to me.
Maybe it could use more contrast too? Your player is rather dark and REALLY pops out on the tileset with little to no dark colors. Tho you could probably desaturize outfits and heads with a script too.
Tiles look good tho

They really remind me of link to the past for some reason and make me wanna demand a chicken statue with the n/s/e/w around it XP
