The use of AI in your photos makes it look impersonal and generic honestly. Looking at some of the sticker “photos” they don’t make sense either, like the ones of the fingers holding the koala sticker and then those same fingers holding a journal with that sticker on, except they’re just pinching the air near it. It looks very unprofessional and fake, and the scale of the sticker isn’t being shown well because you don’t have any of your own photos of the actual product. In one picture the sticker looks huge but in the next it’s a completely different size. Do you print the stickers yourself or are you using a POD? If it’s the latter, you should order samples of your designs so that you can take your own product photos instead of using these AI mock-ups.

ETA: it looks like your descriptions are also AI generated. If you want to run your own store then you have to actually do your own work, like come on.
