Pilots model, too much stiff/sitting back?

[5-in-50]

I agree with the OP. When I fly, my shoulders don't touch the seat as my arms are extended to the flight column and other instruments. My lower and middle back is in full contact with the seat however.

If the CoD pilot model had more curvature to the spine, the chin would be further away from the chest and look more natural.

Low priority fix, but well spotted
