My large ship repaints I've done so far (I don't own any YT-1300s, as I play largely imperial).
The Firesprays are the color schemes for the generic bounty hunter and Kath Scarlet, I'm being highly tempted to pick up a fourth firespray and do a Krassis, but I can't decide on what color the back part of his ship actually is or if I'd ever have a use for 4 firesprays (we play 150 points currently, so I have run a triple firespray list).
Fairly certain the Lambda's non-canonical. Just my own little flagship.
