I was trying to place the first model's head in one of the "rule of thirds" hot spots. Plus, I took this before I knew about cutting off people's limbs. If you saw the others... oh goodness!

And I agree with the clothing statement, thank you for pointing that out. I'm a guy, so I don't really know women's fashion very well. But a female perspective tells me her wardrobe is distracting, which is good to know.
My camera doesn't have any of that TTL flash stuff on it, and to further that, it has no way to shoot at half power or anything. I had the flash EV set at -2, the lowest it would go. But I should have gotten farther back and zoomed in more (used my feet as a diffuser... haha

) And in the future, I'll try not to place my model at a higher perspective than the one I'm at. As you said, I got lucky my models are naturally photogenic.
I'm not saying these to discredit your observations, but only to tell you where my logic is in doing what I do, you know? I figure maybe if I tell you why I was doing something a certain way it will help me improve. But maybe not...
Also [gloat] I did some PP on the second one! I took her teeth which were more yellow, and lowered the saturation on them. I figured it would keep some natural yellow in by doing that, but bleach them out a bit

I also got rid of her red-eye issues.[/gloat]
