Food Delivery App (Fude) - Design Challenge

I'm creating design app from Food and Activity theme I got when doing a roulette with my design team.

So, by not making it difficult, I decided to create a food delivery app that may help user in getting healthy food everyday.

For the first Idea, I created a persona with a story that related to some problem about getting healthy food, then brainstorming idea, mapping the idea with mind mapping, create the basic flow and make low fidelity prototype with those idea.

In the process I had some difficulties with colour, because I want to use white as the base and fresh colour such as yellow and green, but sometimes it is hard because the contrast is really high, then I try to compliment the bright colour with some gray-ish and darker colour.

Okay so this is the result, I would be glad if you could give me advice on how to make it more acceptable for user, thank you for reading this description, stay safe out there and have a nice day.
