I concur with my esteemed colleague, Mr. AmPM about the mountain. You probably want to make it about a third of that height and smooth it out. Base ground is height 10, you probably never want to exceed around 30.
Also:
- For screenshots, turn off fog. Go to the "Atmosphere Properties" menu and uncheck "fog"
- For the area of parked vehicles, take out the mud tracks and lay down either dirt splats (look for "sandy" under nm_road_dirt) or concrete splats. Look at St. Hilliare
- For wrecked vehicles, It looks strange to have many identical wrecks in a row. I would leave only one or two (at most) of each type of vehicle. Spread them out and point them in different directions. I know the look you are going for, but it won't work right.
- It looks like you used a spline for the row of craters. Use splats instead and don't make them in straight line. Use about 2/3 as many craters and scatter them. Bombs don't fall in neat straight lines.
- I like the main road and round-about.
- Examine the railroad splines. Something doesn't look right with them. Look at photos of rail yards for inspiration. Try google image searches like this
