Jeff,
One small critique on your crossing and a suggestion...
The critique is that your white lines are WAY too close. I understand the need for selective compression, but they definitely should be back a scale 10 feet at least, if not more. Even that is close, but it will look better.
The suggestion is to clean up the edges of your road a bit. If you look at a typical asphalt highway, the edges are usually pretty even, unless it's very old and crumbling. Try smoothing yours out a bit, and then put some gravel edging on them.
Here's a good example of what I'm talking about. Obviously this is a pretty minor road, it looks like it's only one lane wide. Still it's got gravel shoulders and no large drop-offs. It doesn't have any stripes, probably due to the road being tar and chips.

PS - Yes, I'm being picky, and no most folks won't notice this stuff. Part of what our company does is install crossings and signals, so I see stuff most folks never know exists.
