Have you thought about taking a picture from when you create a character? You will get a preview of every class/role in a specific class outfit. This one here:

The benefit would be that every race is wearing the same outfit. Plus you can easily take a series of pictures from the same angle which makes the texture creation process alot easier.
Have you thought of making the portrait texture your health bar texture?
Don't get me wrong. I'm just posting ideas that came to my mind.
