this illusion is kcoming in inda low on my trusty freaky-deaky meter. if cindi lauper is a seven on the freakometer, this might be a three and five eigths.
Bad cropping. Is the reason you cut the top off because it would have given away how you accomplished the leanning? Too cluttered with light here and there and not good focus on can .
Good trick, is it balanced there or did it have some help? Very sharp focus. Don't mean to be pushing my ideas on you, but a suggestion? If this is really balanced, try this photo at bench level and prove it, and show all of the top of the can to prove there's no string holding it up, either. The best magic leaves less questions to the viewer's eye. 7 Swash
Are you supporting the top of the can with your finger? It would have looked better if you'd blu-tacked it to the table in that position, and shown us the whole can. Not a bad effort though.
Framing slightly off, would have been nice to see the top of the can (but that might be where the string/hand is!) I wonder why black & white was chosen though.
