I got a Dollchateau body that I wanted to use with a Unoa head, yet I also got the Cerisedolls head I totally love. The unoa head suits the body better in terms of color match and proportions. It also suits my character somehow better. The cerisedolls head is just prettier (in my opinion).
So I made basically the same face-up on both, and took some pictures to see how it all works out.
