Hi fluffyduckyy! This sounds like a great project an isekai romance visual novel with Sun and Moon aesthetics is right up my alley.
I specialize in clean 2D anime character art and 1-on-1 concept design. My workflow is fully transparent, sending updates at the sketch, line art, and color stages so you have total input. My custom character rates typically range between $80 and $120 depending on the complexity.

Let me know if my style fits what you're looking for!
