Oooh, shiny! *_* ...I like this map. You went a bit overboard with the placement of plants and stuff, but the result is actually pretty good. Just be careful when placing stuff that could hamper the player's movement. (Rocks, Tree trunks, etc.)
Aside from that I'd change two things: I'd make that tree on the middle a bit bigger if it is supposed to be important. And I'd change the colors of the background for some slightly more vibrant ones, so they match the colors of your tiles.
