Let me start by saying that Mike had already designed the logo and website, and wanted me to use the existing branding and colour scheme he already had in place to come up with a rocket illustration and email template designs. (I recently noticed that they seem to have changed their home page and some design elements on the site).
The rocket illustration is used when you send a file using Kicksend’s file sharing service. Once you choose the file you want to send and the recipient, a pretty cool animation happens with the rocket blasting off. Originally a thumbnail of the file was going to be shown in the window of the rocket.
I then went on to design some email templates based around what I had done in the rocket illustration, see one full size here.
