Skin weights for the arm are terrible, I can't animate with them. I purchased the michiru rig and expected this one to also not have controls but at the least have the skin weights decent. The other weights are ok, it's just the shoulder/clavicle.

More a neutral review, because for 13$ you cannot expecting a good model. I also encountered many problems with just the head and hair alone. I had to do quite the number of morphs myself , because the base 7 morphs where kinda lacking and all the 7 morphs shiftig a black plane from the teeth. So if more than one morphs is active it shifts the black plane out of the head. Very bad design. Also a bunch of hair bones where wrong weighted and had to fix that too. And the texture is very dark. so had to redo the textures for head and hair to get mroe colors and more decent lines out of it. And other little issues with the geometry, like no split edges on the hair, etc. But in the end it saved me a bit of time, so i not had to do the base face + hair from scratch.
