I just had look into your website. I Have few suggestions on your store.
Your store/website logo is not much attractive to view. You can think more creative design on your logo, It's your store's brand.
And banner image also much looking.
And i have obsereved some of your products gallery images are not in equal like https://www.handmadeartbymariailiescu.com/collections/set-ring-napkin/products/ring-napkins-decorati... check it.
Have you created your website Facebook and Instagram pages? Am unable to find your website social media pages. I suggest you can add/create in your website.
Your top image looks blurry. I would get a clear one or remove the image slider entirely.
Your product titles are wayyyyyyyyyy too long. Shorten them to 5-6 words max.
add trust seals below your add to cart button.
Are all of these handpainted? If so i would make sure to put that on all of the titles as well as the descriptions.
I woudl google other sites in the art niche and see what they are doing right. Then copy those elements onto your pages and site. You can also pay someone on fiverr to give you optimization tips to help your sire convert better, https://www.fiverr.com/share/llNlg
I am new here and I need some reliable opinions and suggestion to my website www.handmadeartbymariailiescu.com.
I waiting for feedback.
Awful logo change it. Horrible main page image change it. Terrible grammar in your speech on main page correct it. Why are you selling artwork for $35? Can't you sell it for $350? How did you derive/get to this price? You need to talk more about the painting and what it represents like I am not buying a drawing of a squirrel I'm buying what it represents. You think I would buy the Mona Lisa painting just because it is a white woman?
