Your profile looks fine! The only thing I would suggest is that you include hashtags of things that interest you. #\DogsOfMastodon (without the \) might be a good one, or just #\Dogs. Look on @marcelias's follower list for people you recognize, see what hashtags they are using, copy their list and put in your profile! That will make you more "findable" as a person of similar interest in the many *MANY* things you could be discussing with others here on the network. :)
Welcome!
