my first pullip, a Tiphona!

[Alliecat]

Yay for your first Pullip! They are pretty striking when you see them for the first time in person!
I think your photos are fine -- I especially like the one with the unicorn. Making them look 'alive' is a challenge I enjoy too. I just try to make the poses as realistic as possible -- would a real person pose this way? -- and make sure they're looking right at the camera if they're supposed to be. If not, that can be OK too, like in your first pic.
No doubt you will find that one leads to more....
