my thoughts: great shot, bad photo manipulation work... i gather the tigger tatoo on her back is real, but the tiger lines that were added to her bum and legs look funny...like.. unreal.. I'd have added just a hint of lines on the edges of her legs and hips, in order to avoid the mess in the part where the tigger tale joins the lines..
Oh and the background looks pixelated and not quite part of the pic cos even the light direction is different :/
Not that I know much about art or photography but the background looks very flat compared to the model. Maybe it would look better if the background was darker and the tattoo was more of a high light than just part of a complex picture.
