Dude, this is a great tribute. We all know that after touring so much and using strange toilets, Peter loved the idea of defecating in a familiar bathroom at his own leisure. Who knows how many riffs and lyrics he came up with while on the toilet?!
Oh god yeah. He didn't look good at all. I knew something was up after reading about his earlier drug problems. I think losing his Mother hit him pretty hard as well. The death of a child, partner, or parent are the worst things that can happen to anyone in life.
I'm still in shock about his death. His music helped me out a lot when I was younger. That, and he wasn't some arrogant idiotic rockstar. He was a decent human being, openly admitting his faults (if any). At least the music still survives.
