I have a new pillow designed and I would like to creatie 4 graphic illustrations of how this pillow effects the cervical spine.
Picture #:
1- shows person in back sleeping position with pillow supporting cervical spine
 with the proper cervical spine curve being emphasized.
2- shows person on side sleeping position with pillow supporting cervical spine
 leveled with mid head line in line with midline center of body.
3 + 4 - showing detrimental  effect with traditional pillows. ie: back sleeping with high pillow, pushing head fwd. Side sleeping showing high lifting or neck kinking.

Illustrations should monochromatic, 600dpi and present proper vs. improper mechanics of spine, with some nerve and soft tissue effects,  
and demonstrate the 'good' vs 'bad' effects.

I thought a 'see spine through the pillow' type illustration would be best.
