My next wallpapers in my SRW series of wallpapers is of Kusuha Mizuha, pilot of the RyuKoOh, and unlike Lune her mech isn't human like and doesn't get more fan-art than her. Matter of fact there's too FEW art, official or otherwise, out there. It was hard finding something good to use for the RyuKoOh. The background is indeed The Great Wall of China. See, in Original Generation 2, Kusuha and Brooklyn aka Bullet both find the RyuKoOh, and KoRyuOh (they transform into each other) in China so I was like, "that fits".
RyuKoOh and RyuKoOh both mean "Dragon-Tiger Lord" and "Tiger-Dragon Lord" respectively. So she pilots the "Dragon-Tiger Lord" version.
In "version b" it's all about Kusuha Mizuha herself so there's no RyuKoOh, and there's no China background, plus it's Kusuha in her other outfit instead of the orange one because I felt that gives a neat contrast with the orange background.
Like version a the tall widescreen size has black bars.
