I must admit that when I first saw DOTM, I was disappointed by Wheeljack's appearance, specifically his head design and voice. I thought that he resembled Albert Einstein! I liked his alt mode, and thought his actual body design wasn't bad, but his head was, un-transformer like. To me it was a total departure from what they looked like. Enter a concept drawing by Mr. Sharkey that I thought was totally astounding! If they had used this design for the film, as well as the toy, I think that we would have seen a completely different reaction from viewers and fans alike.
