PastelCore Coloring Help + PSD (Patreon)

PastelCore (https://twitter.com/Pastel_teeth) Asked for some help shading one of her pieces, and also wanted some tips on rendering cum. This wasn't as refined as I'd normally do, but it shows some of the important principles I use for shading and shadow. Let me know if any of you would want to see a video based tutorial like this.

I'm also including the PSD so people can learn from this!
