Wonderful image! This is simply amazing, I love how well this works; although red used for a non-char mobile suit is sort of weird; I think this is wonderfully done. The style it's done in really gives it that anime feel, but that bit of realism that you always appreciate from gundam. Although this piece is rather old; this is my first time seeing it and I had to comment. Kudos for staying fairly calm on this wonderful upgrade of the Neue Ziel, and making such a wonderful concept Mobile Armor.
Well, there's the MAHQ page for it: [link]
And there's also a Gundam War card for it in Japan: [link]
If you're interested, there's also a Mobile Armor called the Zero Ziaru which appeared in the manga Char's Deleted Affair. It was never finished in the storyline, and as a result is rather simplistic in design.
Here's the Zero Ziaru on MAHQ: [link]
