The anatomy is complete. By now I'm starting to have a bit more clear where do I want to go with that character.
I used a Biped as bones and Skin modifier for the rigging. I did a very basic skinning at first stage (when I was not planning to add more characters) and I after I was happy with the pose, I took a snapshot of the mesh and started making it all look better. Also, I opened the mouth editing at vertex level.
had very clear that I wanted some demonic-angel look for the characters, so I modeled a tail to contrast with the angelical wings. Also I was looking for a very dinamic pose, so I modeled the tail in line with the direction of the action. As it is an independent object, and the back is not going to be seen, I do not need to model the intersection with the body
As you can see, the back of the model is very hard tweaked to make it look good with the camera, but not so good in other angles
The cloths. Well, I'm not too sure why they should be wearing cloths in that place, but they help me to give more action to the movement.
