Kreuzer, Strategic View Map {WIP}

[Steel General]

That is a huge map, and looks pretty good so far.

For snow you could mix in some blue (or chooses a more bluish-white) and then add some clouds/noise or texture/pattern to it.

You could try putting a bit more blur on the area in the lower right, not sure if that will fix it or not.

Oceans - I think a darker color blue would work better (but that's more of a preference thing), same options here as with the snow (clouds/noise/texture). You might look at the Finished Maps forum find one that appeals to you and contact the artist to see how they did it.

Other than pattern overlays, the easiest way to add texture is to render some clouds then run the lighting effects filter on them...I'll attach two screenshots of the settings I use. Set the layer to multiply, overlay, soft light, or hard light and turn the opacity down to suit. Then use an eraser to get rid of the areas that you want to be flatter. The first screenshot gives more mountains and the second screenshot gives more undulating hills. Also, the second screenie shows 5 lights, they are all the same settings. Click on the little light bulb icon to add a light.
