I had this scan on hand, and I was suddenly struck with inspiration. So, Yoko. I fiddled with the sky a bit (originally it was a blue afternoon sky), tidied up some edges, put a reddish tint to Yoko herself, and added a sun in the corner. Ultimately, I think it turned out pretty well.
A version without the title (4:3 resolution) is available here.
(Gurren Lagann will air this Monday! I set my VCR already.)
