This gif is reposted a LOT so I wanted to archive it, but it's hard for me to tell if this is even the correct source.
The artist who posted it didn't post any other drawings to any arca board, so I don't have any higher res than 200x200, but it's the earliest instance of it I can find anywhere, and any arca posts of this or any emote from this source seem to link back to it.

If any better res or source is found I would highly appreciate that.
