I'm not sure the emboss is 'ugh', but I would suggest that it be toned down a little. Also, there seems to be a bit of a drop shadow on the mountains that makes them look a little like they are floating? I'd definitely suggest placing the mountains beneath the grass layer and then using a layer mask on the grass layer to reveal the mountains. If you use a soft edged brush then the edges of the mountains should blend into the grasslands.
