How are the old images for Ixa's Save Mode and Burst Mode superior to the ones from Kamen Rider Official? I know the wiki has a preference for Rider images facing forward as much as possible. However, the old images were presumably cropped from a book scan, as you can see the edges of the crop and there are reflections due to the laminated material, making it more difficult to make out details and lowering the quality of the image.
On top of this, the KR Official image for Save Mode is already forward-facing, so I don't see why you rejected it. Even ignoring that, there have been cases where images of Riders facing slightly to the side were chosen over others because they were better in other ways. You can see this with the images for Den-O's Plat, Rod, and Gun Forms.
Chozenshu of Ghost does have multiple Rider Forms image, but most of their body part are covered by japanese text and other form's body part, as well as Great Eyezer, so unfortunately it is useless, we can only wait until Kamen Rider Zukan updated Ghost.
I saw the picture of Geiz Majesty you uploaded it looks pretty but I have a question and its for anyone who knows what im talking about who thinks what they did for Geiz Majesty's armor you know where they put the ridewatches on his armor how many people think that that was how they wanted to do the armor design of Grand Zi-O.
