wow that's really a very detailed references. and a very pretty creature. I really like the way you did the body and the head. it's super cool. well actually the heads. the humanoid face is also pretty cool! you did an amazing job!
I have some fears that if you use the separate face as the reference it won't fit XD! Oh man hopefully I'll get my hands on the guy for you I think it took a lot of time.. perhaps 8 hours or even more, unfortunately. 3 days totall with eating going out and stuff xD
