Originally, this was a frontal shot of a door embedded in a tree trunk. But the image looked much like a bleeding vagina (due to the red) that I decided to paint over it (you can barely see outline underneath in the door area) and evoke something a little more geometric.
Quick lattice set up a grid for perspective – once again, a little distorted.
Fixed up the perspective with the Umber wash linework.
The final piece with pastels and dark washes – complete with doorknob.
