Bahahh, brilliant avatars! If you want a nice smooth transparent background done in Photoshop, it be easy with GIF's! No nasty pixel edges to get your clothes caught on either.
When going Save For Web, use the Eye Dropper Tool to select the background colour you want transparent. It will become selected on the GIF colour table/pallete on the right. From there click the Maps selected colours to Transparent icon (it's the one underneath the table beside the number of colours in the pallete), save and bobs your uncle!
Or you can simple have the background transparent and when you go Save For Web, make sure the GIF is transparent and give the image a Matte, in the colour that the image will be placed on. Nice
I dunno, I like the polaroid-effect one, it's so utterly different from everything else. I doubt I'm the only one, either
I like the four-coloured S2000 better than the tri-one. I like both of the Mini ones, and I clearly remember it from that week's comp, too.
At first I was going to suggest the polaroid shot would've worked better if the top shot hadn't been rotated slightly, but the more I look at it, the more I think you made the right decision. If it wouldn't have been rotated, I can see a bit of visual confusion as to the depth. With it rotated slightly, it becomes much more apparent to the eye that that picture really is above the other one.
