Got an emergency tonight: finish this, one way or another, and I went for full colors! Once again, I'm not a coloring artist but thanks to Procreate on Ipad pro it feels smoother & easier. I'm pretty happy with the result.
Still the end result needs to be enhanced in Photoshop to my taste, I suspect the Ipad screen to have higher color contrast. I mean it's gorgeous, but when you switch to another screen, the artwork needs adjustments.
