My first completed model since FFF's 31-days contest in early 2009. Geez.
This kit was long overdue to be finished. I bought it when I was on vacation in Tokyo in September 2008; testfitted it in November 2009; took it apart to mod after the 31-days back in March 2009; and it sat there, skewered and ready to prime until the end of November 2009.
I wanted my 1/60 Exia to be a little special, and different from the rest of them out there, so after Gundam 00 ended, I figured I'd make mine the Repair II. I conveniently waited for the 1/144 HG version to be released first; at least I'd have some decent reference pictures to work with.
The Gundam itself was completed on December 30th 2009, but I couldn't get the blade for the GN-Sword right; had to strip the paint and re-paint 4 times. Ulgh. The whole thing was airbrushed with Tamiya acrylics, and this also happens to be my first time doing any sort of shading on a Gundam.
Anyhow, onto the good stuff.
Full body pic to start with. I opted for a much lighter tone of blue and red (almost baby-blue and pink) to give a softer look. I really liked the "Designer Colors" for the 00-Gundam, so I went with something along those lines. I also painted the top/middle of the shoulderpads white to break up the large blue surface.
