Elena and Nickolas Cook-off

I had an image of Elena (by Blueberry-Cloud) and Nickolas (by Nini-the-kitty) cooking to see who is a better cook in their family. (I even wanted to buy it as a poster, but I'm not sure about selling it to public yet)
What I liked about this piece, is the shading. The technique I used was fast, but looks amazing!

Time: 4 hours 10 minutes

Elena belongs to Blueberry-Cloud and Nickolas belongs to Nini-the-kitty
