All TF images here, except for the main one, are from the Transformers movie and/or associated website.
The full body pic of Optimus comes from [link] , and made by Nico Di Mattia (note that I left his signature on the left arm, figured I needed to leave proof where it came from... and it works I think).
This is one of two versions I futzed around with.
For this version, I put the Side Profile of Optimus facing the Earth....
