Avatar: Rocket is telling Quill that "That's a terrible idea". Why I chose that scene, Rocket's just looking cool in it - sometimes I do consider real life feelings but I think this time was just about looking nice. As for why Rocket is the avatar, I mean... it is what it is.
Signature: Up until yesterday it was a screenshot from a very pretty place in Ori and the Will of the Wisps. Now, uhhh, it's self-promotion for my music project.
