Ouch, not where I would want waldo to be [behind blinds], next he will be behind bars. lol. Nice lighting and focus and waldo is hidden enough to make you look but not to hidden to not find. Your picture seems to be on a slant. A slight tilt crop to the left would of helped. Good job!
Gave me a good laugh, but the picture as such isn't very interesting. You might have straightened it, turned it b&w or duotone (as there re no interesting colours anyways). You should have filled the bath tube, and as you couldn't place a second person in it, one of those yellow ducks and some foam, maby a bottle of champagne and a book. That IMO would have made it a much better picture. 4.
