I think you should remove what appears to be lightsabers from that picture to give it a more original feel to it. It doesn't look bad, but the second I saw it my brain said "STAR WARS!".
The path to Maribor is awesome, but there's a little flaw in the perspective on the spaceship itself. Personally, I think you would add to the atmosphere if you would remove the spaceships alltogether, and make just a bit more of the city visible.. if you know what I mean?
You good some good talent in you man, keep it up.
