Which version do you prefer and why

This is one of the young ladies fro the local college.
I know not many of you have an interest in people photography, but I would like to know how you think I am doing.

I prefer the color version, but IMO, the biggest problem here is her hand, especially elbow. Its just waaay too big and quite unflattering.

Thank you for pointing out the obvious. this is why a second set of eyes can be a big help

Which lens did you use, and at what focal length (if a zoom)? Generally, a longer focal length will give a more flattering view.
