Hi @Janadabagma
At first glance, your store seems fine: dark colors, but also dark images that match.For AI images, yes it is a bit noticeable, but it looks solid. It depends on how they look in reality. If it is 100% match, then it is fine. But you can imagine issues when a customer acctully buy and gets something that is different.
Edit: I saw some products that have a black background as the second image and that one might be the real one, and the first just AI-enhanced, right? Then it is fine.
As @Mustafa_Ali noticed, you have a big space at the top. It comes from the Custom liquid section, where you placed some CSS styles to hide things. Note, you should have used the Custom CSS setting, for example, in the Header, or just place it at the end of the base.css file.
Also, that welcome message just takes some space, you see it once, and then it is not needed.
The product page is solid, but the info part feels a bit narrow. As, for example your product name can take 5 rows, which is too much. You have both some customer reassurance icons and payment icons, which are good trust signals. You do need some reviews, which would also help. And please, make that add to cart button full background color, white or any other accent color, as in the Dawn theme, which is the default, but for me, it does not make the button noticeable. It looks like an input field with a label.
For me, the third product image Us vs. Them should be a section, as well as the fourth image, dimensions. While I think Google can read from images, not sure if that counts the same as text for SEO. But also, it should be clearer to customers as a separate section.
About us page ius bit generic, maybe AI-generated, also, it does not say much about you personally.
Good luck, you have a solid foundation, but it is a tough market.
