After a little break, i continued mine, so here is another WIP, will probably make another after this, correcting some snow lumps and stuff.
Edit:
New Wip, deleted nearly all of the snowlumps because well, they didnt look like they was supposed to be. Also changed sky. If there are no more suggestions, this will probably be my final.
The moon does not do any justice to the terrain. It in fact looks attached to earthly constructions in the night-pic (No.2), as if it is some kind of communication tower.
I suggest you removed the in-built snow, it only manages to add unneeded visual noise.
The snow model's edges do not smoothly blend with the base terrain, making it look less realistic. However, it looks a lot better in the pic No. 3.
I am not sure how a modern industrial area is having any relation to the statue that you are using. I suggest you ruin that part a bit more, so that they look more like ruins than remnants of a previous era that doesn't aesthetically fit in the background terrain.
In the left, it would be really cool if you used a few tree branches going all the way towards the center of the screen. The shot would look much better that way.
The height of the surrounding cliffs should be a lot more varied.
Use lighting to add atmosphere. You could in fact use blue or yellow lights (located
here) in two rows, on the bridge, one row from the left and one from the right.
I assume that you are using the Eerie Fog from UTM; try using the Glow model with Z set to 0.
Thanks for the suggestions, i'll work on these things then. I downloaded your pastebin but i seriously dont have a single clue how to use those files lol, can you link me a tutorial or something please?
The file is not created by me, just for your information.
There is a map located in the *.zip file, which you can open in your editor and retrieve the Light models that I am talking about. Light_Yellow/White/Red/Blue are the mdx names, if I recall correctly. Just import the skin with no path (remove war3mapImported\) and the model(s).
The files are individually placed in the *.zip as well, but it may take a lot longer to finally get them.
