It's sort of a transcendence I suppose, being completely enshrouded in pain, torment in the physical world, but then breaking through - maybe even because of the pain - breaking through or being caused to transcend to a state of inner ecstasy, euphoria. Perhaps like the pain is all so much that it's just TOO much and so you realize it doesn't even matter anymore. I painted it a long time ago though, but I'm pretty sure it was along these lines.
Nice gallery btw, good work! Where did you see this drawing btw? I'm just sort of curious because today I suddenly got a wave of attention on it out of nowhere, and I didn't submit it to a new group or anything..
