Environment Concept Artist (Videogames)

We are looking for a professional environment concept artist for our indie videogame focused on stealth and parkour. If you recently graduated with a professional degree in art (or a closely related field), you are also very welcome to share your portfolio. We are working on the visual development for our first location. The task will be to spend several weeks supporting this visual exploration. We are looking for high iteration and volume of work to test different concepts quickly. $200/piece, $70 for sketches. This is a realistic (not stylized) game, so we are looking for stunning yet grounded visuals. We will also focus heavily on architecture development, not just natural environments. If you have portfolio pieces that explore architecture styles, please include them. Some relevant references for artwork level of polish are attached!
