Intro and HELP!?!

Intro and HELP!?!

My name is Jennifer and I set out to find a gardening community now that I have my own house. We are required to have shrubs and such planted but I am not very good with such things - I definately do not have a green thumb. I planted some of my plants and shrubs a while back (Labor Day Weekend) and so far everything seems to be doing well, except for my weeping cherry tree. And, I am not even sure if its doing poorly or its just something strange that I don't know about. I planted the tree in the ground on Saturday evening, and by early in the week the top half of the leaves had turned brown and recently fell off. However, it does appear that there is new growth on the tree. I went to my local nursery and they were of no use... I really hope someone can tell me why the tree lost its leaves so quickly. I am praying I didnt kill the tree... we did follow proper planting procedures so I have no clues... HELP! Behind the cut is a photo of the growth on my tree - I have seen similar on other trees, is it leaf growth or flower growth? I am also including a general picture of the tree - it has lost more leaves since this photo was taken.
