With "/avatar" command, BigBrother currently sends user avatars in default resolution ( equivalent to size=128, which is far lower than Discord's limit ). I suggest sending user avatars in higher resolution by appending query to the avatar URL. Add "?size=4096" to the end of the URL for Discord to return the image in maximum resolution.
Note: valid values are 16, 32, 64, 128 ( default ), ..
