I just visited your site and everything looks good. I did not see a blog. Maybe you can share images of your work via a blog. I encourage my readers to sign up for the weekly blog newsletter. This grows my client list and by sharing my work I encourage new orders.
I only started a few months ago, but my Shopify store is: www.gearbasketmerch.com
I sell licensed merchandise from the app vendors, stylish clothing from another app vendor, and finally print on demand items. The print in demand items have many different themes, but my favorites are those that focus on causes such as epilepsy awareness and suicide prevention/self-love.
I just opened mine yesterday- it still needs a lot of work - I have over 280 listings here on Etsy- (will not transfer all of them) - but I am having fun with it so far! It's like learning another language for me - very challenging - but their customer support is FANTASTICAL - always a patient, helpful human to walk you through whatever you need!!
