It's my first atempt of putting mountains behind the scene - onto horizon and it worked. I've learned you just have to lift objects high enough (above the sky) to put them behind the scene. The image is more realistic this way. However - honestly - I can't put them back to front if needed. :) I've coverred ground with kind of gel, rather then water to make a scene a bit different then usual my scenes are. Hope you'll like it despite it's a bit strange.
