File sharing mock software

As I am going to be making a mock software for file sharing to show in my advert i have been looking at some examples of file sharing softwares, including Limewire and Bittorrent. The following picture is a print screen I took to modle my mock software on.

I have also looked at Bittorent and a few other softwares in order to see what a typicla file sharing software looks like so i can make my own mock software. The designs for this will be posted later.
