I think there should have a back patch with this artwork. There used to have a vintage t-shirt in 1990 with Blue Grape Merchandising. (https://tshirtslayer.com/tshirt-or-longsleeve/1990-sepultura-schizophren...) So I redraw the artwork for their cover to make the schizophrenia more clear to express the madness.
Glittered in the monster's eyes like the vintage woven patch.
