For one of my classes at Wesley (Digital Imaging) we had to design a full social media package (profile pages for Facebook, Twitter, and Linkedin). Each profile page is formatted to the exact specifications required for the respected site with all of them maintaining a consistent theme for marketing sake.
The entire project was created in Adobe Photoshop with an image and logo provided by the teacher. The image was enhanced slightly (to bring out those adorable eyes) with a grayscale version of the logo used as a profile pic.
This was a very straight forward assignment, though the fact that the layouts for each social media site are slightly different does make it a little challenging to create a cohesive piece. Linkedin in particular forced me to rearrange things around in order to fit properly. All in All, a fun project.
