My design for TFW2005's Design a Transformer contest: [link]
The idea was to do an original Transformer concept in the movie-verse style.
Spin-Out is very much inspired by G1 Sunstreaker. His alt. mode is a Lamborghini Reventon: [link]
(Also, if anyone is wondering, the female silhouette in the right of the image is for size comparison (and sexy comparison), I just used a woman as opposed to a man/army guy like I saw in other images.)
