Design 2 different Unity3D levels

Currently, I am working on a video game project and I have completed the design for two different levels as viewed on the attachment, however, a bit of work still is needed. I have a myriad of assets that you will be able to use to give the levels detail, no programming is required and the levels do not have to be complex since they will run on mobile. - The first level is a desert level. Here it will be an endless runner game, so you will be simply tasked with imagining an endless runner level and fill it up with rocks and obstacles. - The second level is a cave, it is much less complex, since you'll simply be imagining it as a platformer adding platforming objects, however, the detail is in making seem like a cave. Each level must be filled with a bit of a detail that gives it your own creative input. Use this experience as a way to improve your resume, I am a very flexible freelancer with a 100% rating and a 50% rehire rate. This will be a great experience I assure you.
