Unless you have a bunch of incriminating or embarrassing things attached to your name that you don't want buyers to see, you might as well just use your real name, as long as it is an easy name to spell / remember. My last name (Benamati) isn't super easy to remember or spell, and most people who say it say pronounce it wrong. So, my wife and I made up a name for our art. However, we have our names in our Bio, because I think it makes sense to say who you are (any shop owner, for example, would do this). If you keep your name hidden and just sell behind an avatar / screen name, you aren't encouraging a personal relationship with your customers. Some people might also be wary of buying from an artist who hides their identity.
In your case, most people should be able to spell your name just fine. You also don't have an unfortunate name for selling art (there are some cases when a person might not want to use their name because of bad connotations. For example: Brown Fine Art).
