Never stop working on, improving and growing your shop. That is my #1 piece of advice for you and any new seller. You never know when that first sale will come, but if you are continually adding new product, improving photos, promoting your work within and outside of etsy, there is a much better chance of getting that elusive first sale faster.
So yes, be patient as in, don't panic or worry. But don't be so patient that you sit back and wait for sales to come. They will come with lots of hard work and commitment. Good luck - you have a lovely shop!
