I would recommend being active in teams, specifically a treasury team, to get added to circles. I'd also work on your tags. Rather than one word phrases such as 'brass' and "owl,' try putting together phrases that a buyer might search for, like 'bronze owl ring' or something similar.
Also, I'd be careful about referring to your pieces as vintage or antique as you do in your titles. Vintage on Etsy means more than 20 years old. Just because a charm has that faux-antiqued finish does not make it antique in any way. It can be misleading to put in a title or description.
Good luck!
