You should submit this to High Moon studios. This looks like it could be the Optimus that follows on from Fall of Cybertron. He has the big muscular looks that FoC Optimus has, but with an Earthly base. I love it.
Nice, but I feel this version's body is too "thick and burly", something which would be befitting more to megatron. Even when "big and clunky", Optimus is still supposed to have a somewhat elegant, nimble feel to him.
This is a pretty amazing design, and with a lot of wires all over the place also, and I don't really remember seeing much in terms of wires (unless they are myomercs), but they feel more like fillers.
This is some amazing work, perhaps better than I'll ever be able to paint, but it doesn't feel like the optimus we all know and love
