Should be 6K pixels tall at 600 dpi After opening thumbnail (Right click - Open image in new tab) to open full size image. I saved it as a png, but dakka is not transferring alpha channels.
Hope this is what you had in mind, just strait and mirrored. If you need pngs with alpha channel let me know.
Also, noticed the in game screenshot shield is probably a bit wider than the ai image, I can adjust it if you think need the shield with that side hole, but also design with both wings, but not to small because the wing corners are running into the frame.
Let me know what you need, I got you on this one.
