Hi Leejay,
I'm a total sucker for models with large, sparkling eyes
Here's some C&C from me, do take it with a grain (or two) of salt as always:
Photo #1: Some girls have a rather pronounced forehead which may take attention away from the eyes, which is what I find the case here. The situation can be remedied by having her hair cover part of the forehead. Because she tied her hair back, this makes the forehead unflatteringly pronounced. Another nitpick is the dressing. I personally don't fancy models who come in singlets unless the shoot setting calls for it. The location is club street area (near Scarlet hotel)? Somehow her dressing doesn't blend in with the setting.
Photo #2: Love her eyes!!! The classy look is complimented by the pendent, the circular ear rings and a nice top. However, her expression looks rather tense, almost forced to smile. Was she holding this pose too long? She has such beautiful eyes, and would be best to let her relax a little if she looks tense. When I detect my models getting tired holding the same pose too long, I let them relax for a while, like asking them to close their eyes, relax the limbs, etc., and let them re-pose afresh.
Photo #3: You're not going to like this particular critique. This is the weakest shot of the lot. Firstly, there's literally no sparkle to her eyes (no catch lights). This kills the picture D.O.A. I understand you didn't have time for DI, but I recommend processing the eyes separately from the rest of the image to handle the levels. Do let us see this pic again after DI. Secondly, she has a rather round face, which does not work in her favour when taken frontal.
Cheers!
