Let's show you it without the sketch.
"What. You're spending hours of work on something not even being featured in the final product?!?"
Yes. I know it sounds stupid, but the above is going to be my guideline for the actual lineart. If it were just a guideline for actual lineart, then it might be a waste, but in addition to that, it will be the guideline for the colors, the shading, the lighting, it'll be the basic guideline for everything, thus, why I am putting so much time into it.
It's officially ready, by the way. All the details you don't see made aren't really necessary, for the aforementioned reason; this isn't going to actually be drawn, and is just here as a guideline for what will be. Very happy with how things are going on him, albeit slowly as they may be going.
