to start with, at least (which I haven't already done):
Irae
Union
Solarian Spacedock
Solarian Ships (done the dread and the cruiser..which are pictured above)
SKM Vessels (Nike, Star Knight, Heracles)
Vasudan Vessels (havent got a clue)
TSI Vindicator
TSI Battleship (i'm working on the dread)
Shrike, the (3D) lightings' fine on my other machine (which is properly calibrated for print...or it should be) so maybe the contrast/brightness on your monitor needs tweaking..dunno. ill have to look on a few other boxes and find out why it suddenly goes so dark.
Alikchi - yep, i'm trying to stick to a similar design ethos for each factions' ships. If I didn't things would probably get pretty messy.
Obviously "2nd generation" sol designs like the irae will look different.
