Drake, Rattle & Roll

This is one of the final logo options for a "Buddy Walk" that is happening to benefit people with down syndrome. This specific logo is for a little boy named Drake and his theme is "Drake, Rattle & Roll". My thought on this was to represent movement so I made the "D" into a car. The lines need to be smoothed out big time but if you have any other suggestions please let me know :) I also plan on adding the text, "Drake, Rattle & Roll" to it somehow.
