That Titus looks a wee bit overtiled. I can understand trying to make it big, but it needs other things on the long flat regions, I think, to help make it look more imposing. I don't want to come off sounding critical, but it's looking a lot like a trashman capship. I think if you had a few random greebles accross the surface, and used them to break up the tile (which could be left intact actually) it'd look a lot better. I think it has potential.
A suggestion would be sort of like how I dealt with the Damocles for TVWP: Like this.
Another example would be the Raynor. Or the Sagitarius model I also tweaked for TVWP, but that's not been shown publicly. (Though I'm sure you've seen it, having been TVWP's help, no? I could show you an image of that, if you'd like.)
