the bad thing is that number of frames are OVERexposed, there's no detail in the clothes. I like the selective color (always been a fan of it). I think you cropped to tight - if you were to print an 8x10 from these, you would have difficult time cropping w/o cutting body parts.
You did something that many folks do do in portraits - 1-2 people (even 3 at time) vertical - GOOD FOR YOU!!!
keep shooting and improving.
I really like the next to last image. As for selective coloring, in almost all cases I'm not a fan. Particularly in this instance, unless the subject of the image is a patch and a blouse. Its very distracting. But everyone has their own likes and dislikes when it comes to things like selective coloring or camera tilt etc etc
