What a nice small corvette...
As for the critics: PD?
Also, using quarter-slabs, you can make crew quarters a lot smaller. For example, the whole bathroom area can be fitted in 2(w)x3(l)x3(h) space (toilet, shower cabin, washbasin w/o mirror) with at least one wall in the same area. Glass doors make a rather nice cover for a shower cabin which can be opened and closed. Ice is a great mirror. Bunks are a bit fat, I'd go with quarter-slabs, maybe with half-slab for a pillow.
To decrease space used, the ship core can be located at the first pilot's/captain's seat's headrest, without a dedicated room. Thus you get a wonderful "Pilot-this-first-person" view from the cockpit. The times of core sniping are long gone.
Even taking into account possible improvements, this is a truly great little corvette and a nice addition for my collection. I just love RP ships, they have a "real" feeling. Not like those battle-oriented ultraheavy drones.
Old habits die hard i guess, i keep building my cores in the thickest parts of my ships.
