Well, I don't really like drawing with layers, just like I don't like using lines. I usually do the first sketch and immediately start painting with color.

But here, for work (and to update the portfolio), I needed to go back to the layers again. And not just to the layers, before proceeding with the color, I tried to prepare a black and white volumetric version in order to use different color blending modes
I feel like a dementor sucked my soul out (⊙_⊙;)
However, I am almost satisfied with the result. It didn't turn out exactly what I wanted, but it's still good.
