This is just a cropped portion of a bigger artwork I drew of my (current) fursona, Scraps. I saw the goofy smile as I was working on it and thought it would make a good profile picture for now.
I originally designed it for Furry Amino which is why it's round, but I kind of like the looney tunes type effect of that on a square background. It should only be temporary, anyway.

At some point I'll upload the full drawing, unless I forget...

(I haven't changed the resolution, I'm wondering how big this image is gonna show up...)
