I had the idea to make myself a crest, so I am :P It obviously isn't finished yet, I need to fix some edges and populate the four sections.

The base shape is the substitute soul reaper combat pass icon (from Bleach) with ears added, that covers anime and furry. The four red/blue sections will eventually be filled with icons representing who I am. Top-left will have a PSP with something on the screen to hint at homebrew, top-right will have something music related, bottom-right will cover game system repair, and I haven't decided what to put in bottom-left yet.

As for colors, the teal is close to the average color of my eyes, red and blue are my favorites, and the grey represents my fursona's fur color.
