Nice use of reds for sure. My only two areas to improve would be:
The base which IMHO needs a little darker in the recess (perhaps a brown ink wash to start with) and perhaps one more layer of highlight
The red on the guns which doesn\'t quite seem to match the red on the armor (and it should). The red on the guns looks darker than the armor and initially I thought this to be perhaps because it was either painted over black on the gun and white on the armor OR not as many layers of red were used on the gun. Now I\'m thinking (after viewing the additional pictures that the smaller surface areas of red on the gun have finer highlights (as they technically should) than the larger surface areas of the armor. I would say you could/should overhighlight the reds on the gun to compensate and bring it up to visually matching the armor, a little trick on the eyes.
Anyway, that\'s just my two cents. Really these are excellent paint jobs and will make for a very nice looking army.
