Not quite sure why I went Cygnus over Draco (or any others for that matter), it's certainly not out of personal preference. Perhaps it was the least changed from the basic hull, I thought the Draco just had a massive hand gun whacked on top but actually the deck is lowered and the subcannon configuration is all messed up. Anyway!
The weird and pointless structures on the bow were a pain in the neck, particularly the lower one. If I come back to it that'll be the first thing I try to address.
The mast above the bridge should be a single structure, but everything I could think of made it look ridiculously big, it threw off the whole look.
Still thinking the Draco next, but the Monoceros should be a straight forward one too.
