Agreed, very nice work indeed!
Not sure what issue you're having with the lighting (newer images look better), but it seems like your sun angle is a bit low, and if you don't have a bright atmosphere, or objects around to bounce light into there, then it will tend to be a bit dark.

It's actually at 35, rather high. In this update I choose different potholes to look at, and lowered the sun to 15 degrees. The issue is the darkness of the colour and how light interacts with it. IRL everything has specular and reflectivity so dark stone is rather lit in the light. Here we just have a ambient reflection map, and a wet reflection map, you pick either, should not have both enabled, but in general the reflection isn't perfect or correct under all scenarios. For example while it looks like wet asphalt up close, the decay over a plane doesn't match a reflective surface IRL, like a wet road into the distance. Basically specular and roughness seems to have "one" condition, and doesn't interact correctly at distance. Without dark objects, like a forest, or city, a wet road, or reflective surface would get rather white in the distance from sky refraction, instead we get the blue sky refractions to a distance and they decay off. I'm sure roughness maps/distance camera could help make gradient better. That's another unrealistic part of Terragen, the sun's intensity (on surfaces) as it hits the horizon is also incorrect. At this point, the sun is a bit dimmer, sure, but it's richer in warming hues, and the sky is still rather bright causing ambient light, and 15 degrees is still pretty high, not even a sunset/sunrise technically yet.
