I wonder if anyone can help with this? Probably not, but it never hurts to ask! (If not, that's fine, no worries, it was a total long shot anyway.)
Tactics Ogre was a Super Famicom game that didn't get an SNES translation in time, but they did go back and translate and release it on the PSX. Fast forward until the modern era, and they have now also given it an enhanced prettied-up remake for the PSP as well.
Visually, the screen is bigger, they actually kept the SF/PSX sprites for the map, but they touched up the backgrounds and scenery, and they completely redid the face portraits. The before and after on those portraits in particular is really quite remarkable.
I strongly suspect that full body versions of the portraiture of at least most everyone in the game exists, because I've seen a lot of it, in varying degrees of similarity to the in-game portraits. For example, things like http://www.creativeuncut.com/galler
And here's where the quest part comes in: the game has lizardmen, and said lizardmen have portraits, just like everyone else. I've been able to find full body artwork of them from before the PSP port, but nothing current, and certainly not the full-body version of that portrait, if it exists.
You know what you must do.
