Aside from painting the engine exhausts of all my ships, here's a couple of ships I've done as complete/semi-complete repaints so far.
I was loathed to get a HWK because I just didn't like the crappy brown colour scheme. So when I finally relented and bought one ( just for the upgrades initially ), it went straight to the paintshop before hitting the gaming table. I started with a medium grey then extensively drybrushed a lighter shade before picking out the panel work with an even lighter shade. Finally finished it off with some subtle white edging here and there and on the cockpit framing, some red trim and did the engine exhausts in pale blue.
Here's a shot taken indoors that shows the colour a little better.
After finishing this off, I was much happier and decided to give it a try on the gaming table. It featured in my next 4-5 games. While it's not my favourite ship, it's getting more use than I first thought it would. Go figure.
I got a second A-wing a while back, and being a big Ralph McQuarrie fan, I decided to give the second one a new paintjob. I have a poster of the Prototype Pilot's artwork, so that was the inspiration for the repaint. I was quite happy with the end result, but even more surprised when FFG later decided to do the Rebel Aces pack with the A-wing in the same scheme. Now I've bought a Rebel Aces pack, I've got two of them, ( although they're slightly different from each other ).
Not exactly a complete repaint. I only really covered the red and redid the engines, but the overall look came out OK and I was happy with it.
