If you couldn't tell yesterday, I'm using drawings that I previously created in my Sketchbook Project journal, taking a picture of the sketch I want to use with my iPhone, emailing it to myself, and adding digital elements. It is quite the process and the picture isn't always pretty, but that's part of what I love about this project. Even the best designers don't turn out 5-star designs every time they sit down in front of the computer (or sketchbook).
Admittedly, I started this design on my commute to work this morning. I already knew what sketch I wanted to use and didn't want to wait. I love how the bag behind the journal is blown out — I think it adds to the concept. I also think you'd all probably agree, this should have been yesterday's design.
And yes, I've got an addiction to bright colors. I'm sure it's just a phase.
