In my personal unprofessional opinion.
No1 - I feel just too much hi, not enough shiro, also not crazy about the hi that goes into the tail, nice white pectorals tho, also feel just too much hi on the face.
No2 - Would have liked more hi on the face, also just feel the hi is too much on the back, altho I must say that good sanke's I've seen sort of have a the characteristic's this one has, would have just wanted more hi on the face and more shiro breaking up some of the hi n the back
No3 - back looks very messy, looks abit untidy to my
No4 - out of the 4 this is my favourite, looks well balanced and clean
This is my opinion, just like I would have appreciated anyone's opinion when I post my similar threads...
