I realized that my guidelines could be a bit confusing, so I made an example art piece to kind of display the details of the request!

Sketch requests will look somewhat like this;

I have three/four line art styles;

Thin line art plus sketch ^

Thick line art with sketch ^

Thick (or thin, I just don't have an image for thin -_-) line art without sketch ^

Solid colours without shading;

Coloured with shading;

So yeah, I hope this helps!
