I don't think the dirt tile looks too out of place.
Yes it is busier, but because of the low contrast in the tile, it doesn't stand out too much.
Edit the hidden passage a little bit to fit in with the dirt paths, and I think it will fit together with the rest of the tiles seamlessly.
I think the cuttable flower looks the most out of place; far too much outlining in comparison to the rest.
I really like your new trees.
The [Zz] box would look a lot nicer if you used the same outlining on it as you did on the [x2] box.
I think the motion blur on the sword looks a little weird. The arch isn't fluid enough.
Otherwise, really nice.
