Hey. Just had a quick look on mobile as I am on the go and it looks nice and clean.
Generally I’d recommend having Vue as a peer dependency for these kind of libraries as this might prevent having two versions of Vue in the dependency graph.
Look into your dependencies as well. For example the gravatar package you include is rather large given that not all users of the avatar component are going to need it and it is basically just calculating an MD5 hash of an email.
