Setting up the main character
The first thing to do in every Poser scene, and which is the most tedious part to do... is setting up the scene.
First thoughts about which figure to use, which clothing item, hair, etc, preceed the actual process. In this case, I chose Laura in combination with the MFD for Victoria 3 (lots of tweaking neccessary to make that thing fit to Laura) and Kozaburo's Messy Hair. As a base for my Engel, I added the Ring Belt and the flamesword. The last part was the Ultimate Wings, because they slow down a scene when they are added and can be positioned without much fiddling to a zero-posed figure.
After the first part is finished, I usually proceed from the bones to the flesh - from the main core figure to the surroundings of the complete scene.
