:) cool looking game, though a pretty simple map; a few things i would change:
add some variation in the trees; also make the grass lower or else it looks like a savanna, unless that's what you're aiming for(in which case make it beige); some hills are a bit too steep; you try smoothing out some of the mountains; also have an escape button to release the mouse and access the menu.
otherwise looks great :D
