Work in progress could use advice

[Ascension]

Here is a little 10 minute modification I did using what you already had. All I did was to add patterns on top of the various parts, threw down some rectangles and put in some roads. Since I use Photoshop I added some drop shadows, bevels, a beach, and clouds to break up the monotony. It's a rather simplistic mod but it's just something done quick to show you the next step in the evolution process.
