I like it, too! When you said "asymetrical bob", I was thinking that it was going to be really dramatic but I think that it's just asymetrical enough to be age-appropriately hip.
I think it's cute and you should give it a try; you can always have it evened up later if you like.
The girl who does my hair is only 27 (I am 48). I give her parameters to work within, and other than that, she has free reign. I do it that way on purpose because I don't KNOW what's current so she keeps me from looking like a little old lady (hopefully). I think it's great that you've got a fresh, young lady cutting your hair and she did a good job!
