Cool concept and all but quality wise this hurts my eyes.
Claredeth: I understand that but the picture would benefit if some of the lines were cleaned. Like the lines at the head.
@Frost I don't think his intent with this was to have cleanliness. I am supposing the way he constructed this was with the idea of a melting and rotting corpse falling appart like a dead fish, you've seen a decompossing fish right.
