To answer the first two questions with one word: Yes.
I love it. I think it is very great that you have done a sort of colage of doodles. It is quite like when I draw during notes at school (and I have been planing on pixeling some of them, but you beat me to it

). My first critique is that the colors are eye burning, and there seems to be no real pattern or compliments or anything (unless maybe you were going for an "off-air" look that tv's do, if which, you did well to achieve). It sucks that the grey section at the bottom (I'm guessing its supposed to be a product package or something because of the "new" label) blends in with the bg of the forum, but thats life I guess. I think that you could make the stream of air from the [bullet?] could use more variety, maybe some more colors being blended together or something. I think the black sector with the blue lines is kinda bad, and I would personally move it to the right about 2 or 3 boxes, because its a dead spot, and makes the viewer lose attention of the picture.
As for the question about death, I counter it with another question: Do we really die?
