This is really interesting work! indeed, the fact that the serpent is not grounded by contours makes it look more alive. Im however perturbed by the knotting : the golden rule of over-under-over isnt consistently respected while i think thats what makes that scandinavian art especially enthralling.
I agree with the above comment. This looks wicked. However, despite this being a design not of your making, i still think you're one of the tattoo artists with the most distinct style i've ever come across, its really rare to see anyone who does pontilism or just lines in such a tasteful, clean way!
