Here is the second painting I did for the Wild Heaven packaging. This was the first cut at it to see how the concept worked before doing the final one.
For something like this I would typically look for some photographic reference to gauge how the light works. In this case it was so strange (guy in a robe holding a candle) that even Google could not help me out. So I had to improvise. I lit a candle, threw on my robe and set the camera for auto. I felt genuinely weird doing it but I had to see what the light did before doing the painting.
