The grass looks like you've tried to hard to make it random. I always find it easier to grab 1 square of tile then hold down the mouse button so the tile will apply whenever i move the mouse and just sketch out a rough shape of how you want to the grass/path or whatever to look like then fill in the edges. It's quite hard to explain so I don't know if that will make sense to you.

Anyway, it's a lot quicker and looks a lot better than doing it from imagination.

Edit:

I didn't want to leave you hanging without a proper explanation of what I said so I knocked up a quick example to better illustrate what I was trying to say.
