I just had look into your website. Great work you have done on your website. I have observed few things on your website.
Some of the item's gallery image sizes are not in equal like https://shebano.com/collections/womens-handbags/products/handmade-bohemian-vintage-knitted-bag.
You can show your banner to your visitors without scroll down the page.
You did great work. I got a couple of inspirations :)
Very clean and nice.
About homepage banner. I think will be more clean look of homepage if the banner will not appear on top... maybe under the "FEATURED WOMEN'S HANDBAGS"
