ExodusUK that's really cool idea!
I was thinking of a black or white background (oh yeah is it okay to have a black background? ...it will be hard to print though...) with a bit hollow pic or two of Ayu and a sorta retro and glittery text with the "A" logo. I'm gonna do golden&pink&green/blue versions of it I think..
This is what I made for the "A WORLD":
And is the international team message part of the text? And ~10th Anniversary~? *feels stupid*
...and I'll change it to .jpg if needed.
