Personally Mike, I think the clean forms, and, (at least at this stage), lack of excessive detail are VERY effective…
It makes it look vey much like the product of a high-level technology, which I sense was your aim. Further detailing, if restrained, and carefully considered, such as small digital read-out panels, and some carefully placed indication of panel fasteners, equally high-tech, will take this baby out of the shop, and onto a high-gravity methane-based atmosphere planetary body, with rediculous ease… 
Very nice, and clean piece…
