Game art for a mobile game

Hello, Following a personal health challenge, I've shaped a mobile game concept that makes it fun for people to take meaningful daily actions in the health challenge of their life, by using the latest medical research, behavioral changes methodologies, and Octalysis gamification framework. I'm looking for a creative game artist, with proven experience, to establish a long-term relationship. The first project is 6 professional photos that represent the main game parts screenshots. I will use these images in a business presentation. I will provide a very detailed specification for each image. Skills & Requirements: - Sketching concept designs and key elements of the visual style - Experience building 2D models for the game assets - Problem solving both creative and technical issues - Designing with the user experience in mind - Excellent communication skills
