It looks to me as though your problem lies with the shop light. You will 
never solve this problem photographically by using such undiffused harsh 
lighting, but that is easily solved. You could go the expensive route by 
using specialized photographic diffusers, or reflectors, or you can adapt 
your shop light by placing a diffuser sheet between the light and your 
subject. A search on Amazon for light diffuser, or diffuser sheet will expand 
those options.

Here is more for you to read:
