Thank you Gabriel. I will have to play around a bit more with nesting, which I can do tomorrow as well…I may have some questions when I give that a go and will let you know.
In the meantime, this is the image setup. All sitters are positioned as in the image below…. except with varying tones and positions. Some are perfect in that they are perfectly centered and plenty of space above the head. Some are slightly off and some a bit more off center which is what is causing the problem.
