I love what you have going here, and don't really see anything that I would describe as an error or that really needs work... With your style of sprites, you wouldn't really want too much little stuff cluttering up your floor, especially considering how you are doing the flowers, but I might suggest simply having some sort of flower other than the large ones you already have... I think it would be something that would benefit your maps as a whole to give them more diversity.
I do have a question about your battle system setup, though, so that we can get a better idea of what is going on there...
I noticed that you have a team, skill and rank switch system... But I ask this: Are those other three spots for other skills (That is, if they learn other abilities than drop kick, would they show up in those empty squares)? or are they for different battle options (such as items, defend and standard attacks)
Other than all that, I would have to say this: I don't think your character and your map sprites really go together... It might be the sharp outlines around the boy character that Mihli is fighting... they don't seem to match the much softer outlines you see on the trees and bushes...
EDIT: Also, Daria, I have to agree, I'm not really sure what the issues are... At least, not the issue with the first one... With the second one, I think I know what he might be referring to as a mistake... It is similar to a style of house I have seen before, but because of your perspective and the length of the roof on the right side, it looks like your building goes like this:
....___
.../...\
../....|_________
./.....|_________|
..|..............|
..|..............|
which would be kind of strange...
