#7 is my least favorite. Its a bit out of focus.
#8 is a gem..thats my favorite. you caught a great image here. Yes, it's a bit over exposed in the background by her hair, but ya know... it just works for the image. I will probably look good in B&W as well but I like the colors. It needs a little tweaking but I love it.
#3 is just okay. dont really care for it myself.
#4 could maybe use a crop.
Overall, I think that your white balance is off but that can be corrected with Photoshop or another program. Maybe just a few tweaks here and there.
Nice eye, you really captured the moment. The only thing that bugs me is the border but that's just me. Borders bother me in general.
