Jungles are just how I do them so, good job there. The grassland looks kinds of stamped...I know the brush used so all I see is brush, brush, brush, brush, brush. Try blurring it so that it blends into the background to avoid the effect. The two sets of mountains in the east are almost all duplicate, change some of them. The red font looks plain, maybe try something with a bit more style, but not too much, and maybe change the color to a dark brown. Overall, pretty good job, just needs some refinement.
