This "painting" was virtually generated using a 3D rendering as basis. The render was created using iClone 5 and the paining was created by running that image through the Dynamic Auto Painter, which to a fair degree simulates the process of painting. I then worked on the image in photoshop to give it a distinctive aged feel.
The model used is not my own, but I have purchased the rights to use it royalty-free.
Feel free to use this in your game or other project. I have found it makes a neat background.
Do note that I am not deeply religious by any means and that I worked on this merely because I found the subject was very responsive to light and contrast work as well as the painting process. If you have a religious argument about this, I'm not the person to contact about it. :P
