Lol <3 Gundam models.
From what I'm guessing, this was probably deleted because of the background. The quality of this is exceptional,
but the concept is kind of lacking. I don't know anything about Gundam Seed, so bear with me :P The only idea
I'm getting at the moment is "this character owns the Gundam at the back". And...? Why is this character
aggravated looking? ^_^' What has that got to do with the Gundam? ^_^'
Simply put, the 3D model of the Gundam at the back is rather disconnected to the vectored character at the front. Yes,
exceptionally extracted, but it possesses a very different quality to the vectored character.
Personally, I think that if you took the expression of Cagalli and made a background revolved around that (explosion in
the back <-- just a random idea, taking note of the lighting) it might work better. Even if you vector the Gundam in
the back to give it a similar quality to the Cagalli vector, there's no guarantee that the wallpaper will stay in
the gallery (because I feel the Gundam is kind of holding back from a really strong concept).
Anyway, just a few personal thoughts- ;)
