Since this is the last of the Overmind stuff, I think it might be appropriate to do a few more WIP shots than usual.
Here is my model, after uvmapping and initial fills. As you can see, while I have used textures everywhere, they're either very specific (to delineate a greeble) or very, very vague (to establish color and provide a little noise). This is how any well-painted model should probably look, during the initial stages- what you're trying to do is to establish form through contrast and color- enhancing what the viewer will see, by using contrast to pick out specific areas of the design.
While sometimes realism won't permit this to be done until later in the process (for example, with the S'44 stuff, they're not really establishing different values on stuff that's all Army Green until the greebling / fading process), with anything that's your own creation, it's often a good idea to follow an illustrative approach, and use light and dark to help break the model up immediately. Resist the urge to use strong textures at this stage, however- they'll just end up being hopelessly noisy, and you'll never be able to greeble with them as effectively as you can greeble on a relatively plain surface.
My folks wanted me to become a marine biologist when I was a kid, and of course I became a techie slacker instead
