Hi! Saw your thread about building a new type of RTS and couldn't pass by. I'm a huge RTS fan myself, especially Starcraft. Your light vs. sound speed concept sounds super cool and unique!
I have solid experience in game design, game development, and 2D+3D concept art. I'd be glad to help you bring your project to life on a paid basis.
My specialization covers both character design and environment art (a heads-up: the portfolio works are a bit older, but my current workflow is highly adaptable and can adjust quickly to any project requirements, leveraging a wide range of tools to achieve whatever results are needed).

If you need a Game Designer with experience in system design, core mechanics, and complex feature interaction, I can share my GDDs in DMs (primarily card game documentation, but applicable across genres).
Feel free to reach out to me here or on Discord: fabu_forster
Looking forward to hearing from you!
