SRD, you messed up with the bow yourself; look at how the bow file is made by others. You need to carefully cut out the same piece! And regarding the model... Why did you delete it? There's nothing лишнее here. Everything is as it was in the original. You shouldn't have touched the bottom of the dress! You can only delete some of the overlays on the dress from the top. I don't know about the flickering; it's all 1:1, so it shouldn't be happening.

Leave this inventory alone. We've already bothered the artists enough. We've been working on this since February. Just bring the overall color of the entire model closer to what's in the picture, and everything will be fine! Yes, leave the boots! I really like them. And the tattoo too.
But we won't be able to make all the heroes look exactly like they do in the pictures anyway... We don't even have that as a goal. Getting as close as possible to the picture is enough.
Regarding the bow: if you clean up this part of the bow, will the bow remain whole? When I erased this part in Faidan's model, the bow became somewhat incomplete
Блистает там воздушностью прогалин.
Но между кедров, полных тишиной,
Расщелина по склону ниспадала.
О, никогда под бледною луной
Так пышен не был тот уют лесной...
