at the risk of sounding anal you dont know what reskin means
khrysokhimaira was an obvious reskinning of khimaira but this is not a reskin
at best you can say they were lazy and maybe took them khim model as a base to create this one instead of making one from the ground up (and as mentioned they likely have already reused skeletons like Tchakka vs Bismarck) but that still is more than "edit old texture and apply glue"
