That looks like it is begging for a horizontally tiling/trim texture. As for adding damage/uniqueness, you could use vertex paint to blend in a damaged trim texture, or you could have damage decals like in this link http://freesdk.crydev.net/display/SDKDOC3/Using+Decals+for+Destroyed+Structures In any case I would go with…
So for the trim method, I would make the top of the base a 4 way tileable texture, but I would have the trim wrap over the top, sort of like this As for the decals, you would they would be on pieces of geometry floating over the surface of your mesh. For best effect you would cut into your mesh where you want the damage,…
I like it, the proportions are maybe a bit too "regular/bulky/box-ish" compared to the ref but the trims look great. I'm not sure about the four rectangles though, they really look out of place to me. They don't look bad themselves but I don't think they fit the base very well, it's very obvious that they're cutting right…
