Half-agreeing here, I like the skybox, however, I think that it doesn't really fit with the theme you're going for. The colors seem to suggest jungle or humitidty, not quite the conditions foumd of most of the world's mountains!
I do like the skybox though, it might be a nice alternative to the Borneo one for jungle maps.
Your map also looks pretty good, first screen may be flat, but it's hard to tell from the angle. I assume you actually wanted people to comment on the map, not the lighting, right?
