So... sketch on the paper and then a short postproduction just to have an idea about proportions.
By the way, this was the first time that I have tried painting on wood and that was strange, because the bruch slip all the time. Putting an acrylic base was tricky.
And here I should have stopped in my humble opinion. Later I have put more blue and made the face more contrast, which didn't serve the best for the painting at least as I see it. Still it looks good :) At least our alien hermaphrodite looks more evil now.
