I’d add a banner and avatar to your shop. Having a professional looking banner helps create a good impression for buyers. Even if you aren’t great with computers they are very easy to make by just using a good photo with some text on the top.

And here’s a link to a free online banner maker - http://www.bannerfans.com/banner_maker.php
Or you this is a link to the Design Services section on Folksy, they can help you create a matching set for your shop - https://folksy.com/supplies/design_services
Hope that helps.
