Im App For ios7

At the first beginning, I thought I would design all the detail part for this IM app, even with a AE animation demo, however, when it comes to weekend, I am so procrastinating and lazy that I've done nothing. So I decided to upload what I've done first.
BTW, I've work as a UX designer for IM app for 2 years, that one is so complicate that I don't want to use it. I feel so lost, I can't make any decisions and watch it become more and more complicate. One day I changed my mind,if i can't design what I want in my daily work,why I can't change it at here.(*^__^*) ...and then i design these ...just for fun and practice...
