I saw your website.
Here are some things that you should add to your website for more improvement.
See your website looks good, well managed and seems it's taken lots of work to make it.
You should improve the quality of the content written on your website. Although your products are very good the description is written for them are not to the point, not effective and also seems low with SEO techniques.
As you have likely to know that a good product description can increase customer trust by 173%.
For this, I suggest you use to Descrii app. It's an auto description generator app .The description generated by descrii is to the point, very effective and even high with SEO keywords .That will automatically increase website traffic and sales.
Hope my information will help you.
Welcome to the Shopify community!
I really like your website banner, its really artsy and appealing. I also enjoyed reading your "About us" page, it made me understand you and your business more, building up a connection. Hence, I think it would be a great idea to add product description to your paintings, such as what aspired you to draw such a painting or what are you trying to deliver from this painting. I believe this a great way you can connect, engage and guide your customers to buy.
Furthermore, since painting quantities are limited I would suggest you to add FOMO, the 'Fear of Missing Out'. By using urgency, you can make your visitors feel like they are missing out unless they order immediately, increasing the chances to convert them into buyers. One app that can help you with that is https://apps.shopify.com/better-countdown .
Next, once you manage to drive an amount of traffic to your site, I would encourage you to use retargeting campaign. Retargeting campaign helps you re-engage with your audience and potential customers who previously interacted or showed interest in your products. By using a variety of creative ads to target these potential audiences and reach to conversion of purchase. You can start by installing the Ako Retargeting app on the Shopify app store. Ako Retargeting is a cost-efficient tool that could help your business increase awareness and conversion. The app helps you get your potential customers back to your website by delivering the most relevant product information to them at the right time, right impression and right cost.

I hope these suggestions will help your business. Good luck!
