I was looking through Coroflot's Creative Seeds and saw this article on The 3 Things You Need to Do in an Interview, since I'm working on my portfolio right now, one of my goals in my portfolio is distinguishing it from the pile of others it is competing against. One way to do this is by branding yourself. Self-branding can be described as how someone can recognize and remember you from the back of their mind just from a simple 30 second to 30 minute experience.
I think good designers have the capability of showing their own personality in their portfolios, while remaining professional, thorough, and thought-provoking.
Here are some designers I admire for their unique and awesome work:
Nancy Wu. Simply Versatile.
Alberto Villarreal. Clean.
Kimberly Wu. Lively.
