I hadn't realized my faces were used by so many people but this is the third screenshot this week using a face from that collection... Yay! I am happy that people like making their game customized with something I so enjoyed creating.
And it is nice to see that that red came out so well, I don't play anymore so all the visualizations I get are from the viewers. Sometimes you just can't tell if the color fits or looks unnatural in game based on the viewer display, and that red was a bit tricky for me because I didn't base it off of any in game graphic but went by what I thought might look good :x
The different hair style is a .dat mod, which is a user end file change. When you put a dat mod into your game, it makes the game load a different file in place of the original (as the file path is the same when done correctly) - in this case, they replaced their respective face with a face from my collection that can be found on neko sentai (no link as neko is, by virtue of its user base and content, NSFW) and at http://ffxidats.caarrie.com/index.php?topic=1311.0
You need to sign up and post in the intro forum to access downloads on the caarrie site, but that is simple enough. And if you have any questions about the process, feel free to ask ^^
