Edit: The reason why Fletching's anatomy is entirely different was because I created this image a long time ago, when refs and description was not very clear so I assumed it was more of a pigeon pokemon. Same reason for the other three pokemon.
Oldish piece, was done for an artbook but progress on the project stopped. I kinda wanted to upload this on the launch day but I couldn't back then >.<;
Good news is that this will be available as a new print for 2014!
