What fun to get to critique this photo. I will start by saying that this is a very successful photo. Good composition, good theme, good lighting. So I will focus my critique on things that may have improved it. I appreciate how hard it is to be your own model and get all the details perfect....
The first thing that struck me during voting was that the panties are not as in focus as I would like them to be. There is a powerful line between your eyes and the panties and I am looking for the panties to be as crisp as your face. F5 probably gave you too shallow a DOF. But you were already down to 1/60th and ISO 200 so not sure you have too much more headroom.
Some compositional observations: The flowers are competing with the panties. Perhaps moving or removing them would have given then panties more focus.
In terms of making this a great photo I think if I were editing this photo I would work to reduce the degree to which my eye is drawn to your wife and her arm at the expense of focusing on the two main subjects - you and the panties. One approach would have been to crop her out a bit more. Another would be to use burning and dodging to reduce the brightness of her arm and increase the lighting on the panties.
You have a great photo here. Congratulations on your placement
I really like the concept here. The lighting on the guy's face is a little too bright. I also find the lady's knee being up on the bed a little distracting
Whoever's other half they are is a lucky lucky person :) Nice take on the challenge and nicely executed. Mucho amusement. My 2nd fave of the challenge and would be a ribbon in my world - 9.
I am sure that he has no idea. Do people really forget to take their underwear with them anyways? I usually notice when I forget to put on my underwear.
