Here's my entry for the Gundam Anniversary contest.
Took about 4 hours.
Some of the characters are blurry, but that's on purpose to try and give it depth. I think it worked out fairly well.
LOTS of credits on the bottom because of all the different characters and mecha in it. The Gundam series it contains are:
Mobile Suit Gundam Unicorn
Mobile Suit Gundam 00
Mobile Suit Gundam 08th MS Team
Mobile Suit Gundam Seed
Mobile Suit Gundam Seed Destiny
Mobile Suit Gundam Wing
