First attempt at map for game

[Ascension]

So I'm guessing that you want the mountains to be right over top of the plateaus that you have...no problem. The continent tutorial does the mountains steps early on but it looks like you've dumped that layer...no problem.

First make a new layer, filter-render-clouds.
Filter-render-difference clouds...do this a total of two times.
Filter-render-lighting effects as per tutorial.
Select-color range=black with a fuzziness of 200.
Hit delete then deselect.

You'll have mountains all over the place so click on the lasso tool. At the top of the screen you will see a box that says feather so change that from 0 px to 50 px. Lasso up a chunk of mountain then click on the move tool (looks like a pointer) and drag it to wherever you want. Once you have your mountains placed make sure to erase mountains that are in the ocean...the best way to do that is to ctrl+click on the "base" layer in the layer stack, select-inverse, then hit the delete key. Lastly, you apply a color overlay of light brown and set the blend to soft light, then set the blend of the layer itself to hard light.

How are these?

I think they look pretty good. Now you just need to cover up those plateau-looking things.
