This is a school exercise we made in team of 3 students (Myriam Dufrier, Romane Govin and I) on the UE4 engine. We had to design a racing game map, from the artistic direction and level design to the post processing effects. I made the concept arts you can see below, created and textured assets like trees,  flowers and flying rocks, some props integration, shaders and post process.
