I was having a chat with Vile-Flesh and decided to doodle something really quickly to show a theory/method I have for how to add light and shade to a pony by applying it like a paste and then smearing it out. Something like that. A bit more complicated but that is the basic idea.
 
Anyway.. the project evolved into this image because I wanted to try some other stuff aswell. So it is a bit strange looking and certainly not cutting edge to say the least. It is based on a veru rough sketch that took a minute or so and just happened to be sooo fun to work with for an hour or so.
