Try one of these. [NOTE: I resized your original image and optimized for web, but it didn't show off your hedgie well (too much background), so I cropped the original image first and then did the same for the second avatar. I wasn't sure this is what you wanted, so I'm attaching the both. They're both 90 pixels x 90 pixels ins size and less than 9K, so they should work.]
