@Pham -- Looks like we are gonna C & C you now like Joe McNally. Welcome to the big leagues!
#1 Not a fan of the crop, but for a different reason. The sliver of concrete at the bottom grabs the eye. Getting rid of that, or making it bigger and giving it some context would help. Ditto for the vertical siding edge bottom right of frame. Its like a dark line, competing for attention. Finally, the speculars on the purse grab the eye as well.
#2 I see mbells points on the pose and hands. I'm okay with the surroundings, cause thats your style. The orange spill in the background though is distracting me. Its like a spot light to nowhere. A wise man once said "anything that doesn't add to a photo subtracts from it" That spill is one of those things.
#3 Her face is lit wonderfully, but the orange rim light is betraying you again. The highlights are visually distracting, as is the heavy shadow outlining her right forearm. The shot definitely needs some fill in that area, or some post work.
As always, I'd be like a little giggly girl if my shots looked this good, but hey, I take pictures of houses. Whadya I know?
