Thanks Rod - I was wondering if the lack of surface detail was a problem or not.
I'd taken the decision not to make the details obvious - mostly because the original Tholians were essentially big, non-descript prisms without obvious engine, bridge or weapons points. However it left me with the concern that the hull shapes would be lost - is that the case? I obviously know what they look like because I created them, but does anyone else see what's there?
