i have seen some huge almost full body tattoos - not solid ink...open, flowing work...most often on women. the level of art involved in this is pretty sophisticated. blending colors..doing fading and shading.... it's always fascinated me...
 the woman  pictured with the upper arm work  - that's a nice piece. it would be too large and dense for me, but it's really well done. they must have made great strides in ink... colors stay pretty vibrant.
