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!
