@Zydragon: Some things I noticed:
This needs more flexible autotile usage. There's only some big portions of the darker green. You should use all of the autotiles and use them a lot more varying than only random areas. Add some darker grass near trees and the others in deserted places (longer grass) or used paths (road-like tile).
Another thing is the leaf roof. It looks really unnatural, looks out of place. Looks more like it's on the ground than on the trees (I'll come back to them later). The random holes in the leaf roof also look quite random, especially when there's a random part of a tree under it.
The plants (yellow flowers) seem to come in a group of 2-3 (near each other). This looks better if you add it to a place where it's expected that they'll grow (not under the shadow of big trees), for example add the long grass under them. Using this you can also make the road to walk a lot clearer.
Now on the trees. The fat bigass 3-tile wide trees look really unnatural when they cut like that with the leaf roof. They seem to go on for like a tile or two and then the top part of it disappears (because the leaf roof looks so horizontal).
My suggestion would be to use the bush-like autotile for the leaf roof, only recolor it to be a bit darker. Add clearer pathways for the player to walk in (or add none and alot of grass and plants if it's a forest nobody passes through). Also I'd suggest to lose the huge trees, and instead add a lot of the normal trees under the leaf roof.
On a side note, here's a map of my own. It's about 3-6 months old, but I haven't been doing anything during that time so my current maps wouldn't be that much better looking.
It's supposed to be a dried up river.
