Good looking troops and engineers. They have to look smart enough to deserve to assault something so pretty.
You're right, the red & white theme is really striking. The drybrushing really brings it to life too.
That ramped walkway with the cut stones and dirty pathway looks *awesome*. The contrasting shapes and colors are very striking.
The gun platforms are another really nice detail. Well done.
If you're still unhappy with the rampart walkways, you might try adding a wash over the drybrushing, to sort of "blend" all the color variations together. A brown should add some squalor, a tan should add some dust, a gray should add shadow; not sure of the best approach.
The doors and windows look great. The white framing highlights totally worked. Consider painting the fittings too (door handles, shutter bands) – either a red highlight or a contrasting black. That should really make them pop.
