DEAR GOD MY EYES!!!!
No srsly, you need to add a crapload of stuff on the ground. By stuff I mean things like flowers and weeds. A couple of rocks, yeah, but too much would just kill the map. Don't go overboard, obviously, but for now, just set down a whole lot of white flowers. You know the weeds? the 1,2,3,5, etc. weeds? set some of them down. Also, one of the tiles is a grass tile, but noticeably darker. Set that with the same amount of randomness, and it'll help. Of course, set all these things down with random, not just in little bunches. Mapping like this in XP really looks a bit better.
The forest/tress thing... god, you need to change that a bit. WAY TOO SQUARE. Get that? It's supersquare, which is simply bad. add bits that stick out here and there, remove one or two tiles at the edge, etc. so it can be better.
Try to enclose the area that one can move a bit; make it a bit more obvious which way to move. It'll be weird having all this space to move, and then suddenly running into the edge of the map like WHAM.
