Julie,
   WOW.  You worried and Worried about this day and these shots are great!  I am sure all the clients are more then satisfied with your results and you should get tons of referral business from this shoot.  Great work and a huge improvement in such a short time.  My wife's favorite shot is the first one of the Pitbull, but she was saddened when I told he about the cancer.  I like a lot of them, but what strikes me the most is how you got 9 whippets dressed and in the frame simultaneously!  
Good work,
Jeff
