Due to the bevel, the "flat" front is incredibly difficult to do anything substantial with. And there's kind of a point to the armor jacket covering the beam cannon and sensor array, since they're both relatively important subsystems that would be exposed otherwise. I tried moving some of the sensor module out so a bit was exposed, but it looked kind of dumb IMO.
The "flat" front with the inset subsystems there has been a big part of the concept pretty much since I drew it the first time, so maybe I'm a bit biased, but I'm also not sure what I would do with it.
I'm only at 7436 tris, but most of the detail I want to put in can go on the texture (which I guarantee WILL make the armor sheet more interesting), so this is one of the last things to decide.
I'll put up a few more views including some orthographic stuff so people can make overpaints if they want to.
