Your website theme looks elegant. You have added chat support, your contact us, and about us page look good. However, I feel it's a little early to give feedback.
If you are setting up a coming soon page for your store, do mention a bit more about what you would be selling here, it's not very clear at the moment.
Also, add a signup option on your landing idea to collect emails of people who are interested.
You can also add some offer for early sign-ups to incentivize them into sharing their emails. You can reach out to these people again once your store is up and running
Cheers, and wish you all the best :)
