your stuff would be excellent for an rts, have you actually got any content into a functioning game yet? or are they still just standalone models.

I think they look nice. Being that your selling them I suppose you would want to provide a color texture to what the potential model could look like for display purposes, and a texture that is easily modable (just the details) so the end user can give it thier own paint scheme without to much messing around to remove the current color scheme. But I think those basic colors are enough to get the creative juices flowing on what they could potentially look like depending on the users project. nice job!
