I like it for the most part... Just a couple things:

1) I don't like the whiteness around the water, change that... Maybe try animating the tiles there, like there are waves coming in or something. That might look cool.

2) I dont like how you made that dirt hole thing so symmetrical, try to un-even it out

3) You need shadows and things, like on the grass-dirt, there should be a small shadow on the dirt from the grass.

4) Work alot on your grass tile(s) try to make it look like actual grass, with blades sticking out. If at all possible, try making more than one grass tile.
