@Sekai: wow, impressive! You must have really worked on those trees, and I like all the animals you added. A few things stick out, though. The bird nests don't look very good over leaves, I think they're meant to go on the branches of the forest tree. The middle and lower left houses aren't tiled correctly... their roof tiles should be more like the rightmost house. Finally, imo the brick road looks off over grass, especially by the well.
A few small suggestions would be to add bushes and shrubbery (you could find some from other tilesets too), and maybe some undulations? (yes, there's elevation in forests too!)
@LegSicon: like luv_kitty said, the hill needs more work. Is there a reason everything is off-centered? The asymmetrical mapping is fine, but I would definitely center the textbox and move up the icon. As for the text itself, I'm not liking the windowskin (clashes with tileset, maybe tone down the saturation); and a less cliche, more subtle intro would be much nicer-- instead of "It all started like this......................." try something like "It began on a starry, cloudless night" (yeah still cliche, but better nonetheless).
