This is one of the styles I trained using my own drawings. My originals were drawn with varying weights of sigma micron pens and they were recolored digitally. Purple is a dominant color in this one, so if you want to tone that down you may need to ask for the specific colors you want instead.

Only "n0vuschr0ma style" is needed as a trigger, but here are a few ideas for other additions: you can add "stipple" if you want to enhance the dotted look, "naive art" if you want to emphasize the amateur hand-drawn look, "comic book illustration" for a bit more refinement and detail, art nouveau for frames and symmetry.
