I tried using displacement maps on the arms, legs, body and head. It makes the face more puffy.
But on the rest, it brings out more detail. I also used 8K textures on the character body. I increased the
normal map between 125-150. I also used 4k shadow resolution. 
I downloaded a free 3D soda can from free3d.com and created my own soda can design. The soda can was created by printable_models.
