Design Mockups for App-Project - UI UX Design draft

We are currently developing an app for a gamification approach to environmental learning for a nature park. Different challenges are set up in a treasure hunt fashion but not linear, so the players can see either a list of challenges or a map with icons for the different challenges.

We have started with a design that we used in our concept for the project.
After the first tests the customer wants a more “secret-agent” - tech-style - look.

At this point we only need some variants of specific icons and a mockup for a basic layout.
(detailed description in the attached pdf).

We need the mockups for the next meeting with our Customer on November 21.

If we are happy with the designs and the work/communication we will post the complete UI-UX-Design as a separate job.

In addition to the pdf we will provide affinity designer files (or pdfs) of the current Icons and designs.

Please start your application with the words "I have read and understood your requirements and are confident to fulfill the job.
