This was my process work when creating my deviantart social networking icon. First I made a vector version of the logo (after not finding one on brandsoftheworld... sigh) which was a slight waste of time after I realized I wanted a uniform style.
Then I tried to base the new icon around the uniform shape available on brandsoftheworld.com. I kept their signature colours while adding the lighter hue to the decorative swoosh in the background. I found that a drop shadow worked best behind the symbol because treatment caused the light green to be lost in the lighter background without.
Lastly, my website that I am designing is a high contrast design reflective of my signature style. This meant that the colourful icons were too attention grabbing on the black and white site. I put them in a style fitting to the site by simplifying them.
