Awesome - really dynamic.

The smoke has some shadow and 3D relief effect on them. If you could get that on the island then I think the texture as it stands is good enough. Then the two would blend better and look more real - or lets say the island would come up to the level of realism of the smoke.

You can just hear the groans after a DM says... You are disembarking on this island - so get your fire protection out.
