App Exploration - Restaurant Delivery Service

This is my first design of mobile app. The app itself is more about restaurant / cafe with the delivery service for the customer.
Every order will be noted in the bottom of the app; The details will be how many order (item) that customer order, the menu, and the estimated price.
Would like to hear your feedback!

Thanks @Aji Maulidio Indra Rukmana for inviting me to this amazing community, excited!🍻
