Food Delivery UI UX Design of Web App

I've made design for web app for making online food delivery from supermarkets and restaurants.

In this app you can : - track your order; - check the map and see where your courier is; - check the timing of your order; - estimate delivery time; - contact your courier via build-in chat or call him; - check you order info and cancel the order.

Would be grateful to receive some feedback. Thanks for checking my design!
