Well, when I'm coloring in pencil, I use peach color pencil and I have limited supply on that. And massive pregnancies take up a lot of peach color pencil. That's why for massive pregnancies requests, like yours, I've decide to do in black and white or digital.
While, I got you here. I want to clarify something about your yuffie and Tifa request before I get started with it. After a long time of thing, it would seem impossible to have them and their sides and by sexy with the big breast that I plan on giving them. However, I found three alternate poses that I could use. And I want to know your thoughts on them.
Keep in mind that Pose 1 won't be able to show the birth. However, I could have some dampness to show that their water broke.
As for pose 2, I would show them at the sides and maybe spreading some melted chocolate on their bellies.
As for pose 3, I could create an anti-gravity belt that could go around their bellies or have the room they are in set in anti-gravity mode.
