Straycat, your sims look WICKED!
RMarques... oh, Eavan... <3
Allemande: YAY! A new voice! Glad you posted.

Actually, the first two male faces in bodyshop are the bases for almost all of the most popularly regarded "sexy" male sims. For tips on what people find attractive, there's a website where they've done face studies (go look up "attractive faces" in Google, that site shoud be near the top somewhere). They have "standard" attractive faces.
I did a test with Mew, actually. I made him so that people would find him appealing (not necessarily sexy!). And made an even more feminized version of him to see to what degree people prefer feminine features on males - Miewtu. 75-80% of people prefer Mew (as a male).
Attractive men generally have somewhat feminine features (full lips, wider eyes), but, they can't look OVERLY feminine.
This is what people universally find attractive (male or female):
- Full lips (but realistically so, and balanced with the rest of the face)
- Open, Bigger, almond-shaped eyes (but realistically so, and balanced with the face)
For male, this is what I have noticed from what people say and download:
- great skintone
- realistic makeup
- hairstyle!!!!! This is extremely important, it changes the whole look of a male sim, makes or breaks the "sexy" factor
- Clothing, to a lesser extent
- How the heck you take a photo of the sim! Some sims look better in certain types of lighting, and in what pose, and expecially facial expression!
Very close-up facial shots work well if the lighting is good. This is becasue if the face seems closer to the viewer, it feels more intimate, like you are closer, and this subconsciously makes the subject more attractive. That's why the soft-lens, Hollywood close-ups are done.
The facial studies show that people presented with a smiling face directed to be looking right at them are rated as most attractive, followed by the expressionless face looking away from the person, then the non-smiling face not looking at the person, followed by smiling and not looking at the person. This is because the smile is very powerful - subconsciously, we want that directed to us, we don't like to see it directed away from us.
The rest is hard to describe with respect to features, but, none of them should be overly exaggerated, and should be well in proportion in relation to each other... see the study, it's very interesting

I found this info very helpful to help me improve on how my sims looked to me - they definitely look a lot better now than when I first started making them.
Samielle, They're gorgeous - the first sim is very cute
Slice, the tattoos really make the sim
Kinako, your Corrolo is a nice looking elf - his scar is quite interesting - is he part of a story or anything?
