As much as I'd like to replace the low-poly with high-poly, I don't think it's possible because the two models animate very differently. If it was somehow done, then I imagine the high-poly models wouldn't be able to open their mouths or move their facial features at all. The only thing we can do is polish the low-poly as much as possible, possibly using expressions captured from the high-poly, with a lot of editing to make it look consistent.
GameCore, the base textures of Banora look good, although like I said, we'll have to do a coloring tint job. It looks like you're using vierock's textures as well (like the floor and maybe some foliage). Please keep in mind, we are not allowed to use vierock's textures at all. They came to the forum and left without much explanation, and if we did, we'd be using it without permission. Unless they come back and give us the OK, we can't use them out of respect. So basically, you should separate your textures from vierock's. Even if you edited a texture, if it uses vierock's as a base, we still can't use it. As annoying as it is tho, if you want to make a new version of anything vierock has done, you're welcome to. I do think the wreath is looking better. And vierock, if you happen to be lurking this topic and see this, we'd appreciate it if you did let us integrate your textures into our project.
