Looser, more fluid drawings
Pattern Design Workflow
Photoshop has great tools for getting the perfect colors and values in your artwork. I was thinking about writing about some basic Photoshop tips later, but what I use a lot are Hue Saturation, Levels, and Color Balance. Be loose, fast and messy about it when trying to find the right palette. Sometimes it helps to be messy to come up with more interesting looks. It is so much easier to come up with good colors this way than being restricted to the color picker in Flash or Illustrator.
