You definitely should NOT move on to a new project. This map has so much promise, it would be a shame to give up on it early. Also, those hills look good when you remove the other elements (at least, I think so), which just goes to show it was the other elements that were the problem, not the hills.

You really should keep going with this map, although perhaps you should also ask to have it moved to the WIP forum (where it'll probably p more comments, anyway; besides, that's how to learn).
