Photo 1: The first photo has a nice look, but there's no clothes, and unless you're shooting for one of the VERY few brands that have poor ads (I include Abercrombie), you see clothes on the models. Sex sells, but sexyness from people wearing cool clothes will sell clothes. It's all about cool people wearing cool clothes, and doing cool things. The clothing can be messy, covered in sand, and wet just like the models you used. However, the clothes should be there.
I think you should grab a copy of GQ or.....one of the other men's fashion magazines (honestly don't know their names......Esquire, maybe?) and look at the ads. The only magazine I've read over the past while is an Esquire magazine while waiting for an appointment, and the 2009 Sports Illustrated Swimsuit Edition.

I didn't see any clothing advert that didn't have the product somewhere in the photo.

Photo 2: It's also photographed well, but what I dislike is their stare. It looks like they're posing. It makes the photo seem ingenuine. If the girl were looking at the camera, while the guy was looking at her face (or vice versa), I think it would be better. EDIT: What I said is not as applicable for the first photo, but you could still apply the same thing. You see ads all the time where one person is staring at the camera, and the other person is staring at his/her face.

I think it's good the way it is though.
Also, like I said to you in
your first thread, I personally hate it when people cut off hands at the wrist, and feet at the ankle. It's just my opinion. In the 2nd photo, you cut her hand where her wrist is.
I think it's absolutely OK to cut off a person's arm mid-bicep, or part-way down the fore-arm. For hands, it's OK to include only part of the hand while leaving out the rest, such as in your 1st photo. For legs, it's OK to cut it off mid-thigh or at the knees. It's even OK to cut off most of one foot but include the other.
I'll admit that it's an old-fashioned rule in photography (although I'm only 28). Since most people feel that there are too many rules in photography to begin with, you may not want to follow it. However, I believe the majority of photographers have very strategic points on the body where they're willing to cut off a limb, and it's not at the ankles and shins.
Look at the GQ links again. Even the photos where the hands or feet are cut off, they're partially visible.
(look at the guy's hand on the left)
(look at the guy on the left, and the little boy)
Otherwise, I like the look.
