Personal, non-professional opinions here:
#1-she looks bored, neck is turned a little too much, would have liked to see her eyes opened more and yeah, the background doesn't really go with her style of posing or clothes
#2-Again, head turned too much, shoulder too high, or something, it looks like she has no neck but an awesome bod. But what I see is head, then body, but no neck, no flowing lines. And she looks bored. Being so hot, I bet she could do a little fierce and pull it off well.
#3-I really love this...now I see personality coming out. Skin is a tad soft for *my* tastes but it's not bad at all.
#4-I like it, but my eye is drawn to the lower right corner at times although I can't figure out why.
#5-The background is gorgeous...for someone else. Overall I like this although I would like to see a different expression on her face perhaps, maybe eyes slightly towards the camera a bit more so we actually see eyes and not just white
#6-Can't say anything really bad about this. The lighting looks good to me.
#7-I see a concrete beam growing out of her head. It seems a bit odd to have half of her in one part and half of her in a different part. My eye goes to the sun beam in the upper left by her head. The strand of hair and the shadow it's making it makes this an "OK" picture for me, but I strangely still like it.
#8-Without the strand of hair and maybe slightly softer lighting I would adore this.
#9-Very very nice. I don't like how her neck appears to be choked by something (earrings? hair?) and it leaves me in question but aside from that, GORGEOUS. Lighting seems perfect for my tastes.
#10-Would have liked to see her eyes a bit more opened here, and there seems like a lot of dead space in the upper left
#11-Seems a bit dull to me light-wise. Would have liked more light on her face, and her looking at the camera or perhaps up a little bit or something. I don't know, something seems off but it could just be the lighting and the chopped off side-of-arm.
Even despite the negative comments I still would love to have these pictures if I were here. Great job and keep on learning...you are well on your way!
