Second interpretation
I like it, morbidly. Others have criticized the style (and I don't know enough to comment), but the technique I think is worth applauding.
I did not identify the skin part as a penis at first. I actually saw the painting in reverse: some malformed, skin-covered thing was being extracted from the skull, and the pincers were there to help get it OUT. Other things to support this interpretation: the penis looks double-ended, the semen is unrealistically solid and thick, and the free end of the organic thing could be the head of something snaking through the steel structure. If you like the dual-direction interpretation, you could try to emphasize it or make the motion more ambiguous.
