Cartoonish Runner Backgrounds Across Different Landscapes

As someone designing an endless runner game for both iOS and Android platforms, I need professional drawing services to bring life to the game environment. My vision is primarily focused on:

- Developing game backgrounds that traverse a variety of themes including nature landscapes, urban cityscapes, and fantasy worlds.
- The preferred style is cartoonish; bringing each aforementioned setting to life using vibrant colors and whimsical elements that reflect this artistic form. This choice is due to our target audience’s preference for this style, so we invite you to let your creativity run free.
- The game will require seamless transition between the different settings as our runner progresses in the game.

Ideal skillset for this project:

- Proven experience in digital drawing, specifically cartoon style.
- Previous work in game environment design will be highly regarded.
- Familiarity with, or willingness to understand, endless runner game concepts and their demands in terms of scenery and setting transition.

Please share your portfolio showing related works - I'd love to see your style and ideas you may have for these backgrounds.
