This is really nice, I typically don't like vibrant colors but I think this works. To make your elements look more in the distance perspective, try creating longated ones - The saving spire works well, but the forest at Sial Flik doesn't work quite as well, if it was wider it would work better, just something I've learned from drawing these.

Also because you put a stroke around the type, you may want to kern the letters to be have a little more space between them so they do touch/overlap with teh stroke. Great job you should be proud of this one, my first one wasn't near as good
