I have completed the model of megatron with a better face now i think. I have rendered him with mental ray (giving it the shine & reflective effect). Still need to play around with the rendering settings of mental ray to get the exact result i want though. Feel free to leave comments. Thanks. I have now added a pic of him in gun mode here, still has the accesorries to be added to him ofcourse (e.g. back handle, front blaster). It is the same model and does transform by the way.
