I'm afraid it doesn't really look, 'mountain like' to me. The edges of the field seem to be too uniform...perhaps a layer mask to roughen the edges a bit? I really do like the twisty pattern of ridgelines within the range itself, but if you could find a way to texture or colour the 'low' areas, that might really make them shine. I think there's great potential in the design, but there's a little more work required, but if you can get there, it will be a fantastic way to do mountains.
