The mold was too bland looking in it's original form. This set of stickers gave the toy some much needed color. From the blue used for the head lights to the blue and red on the light bar. Even the metallic silver on the windshield and windows makes a huge difference.
They even gave the back of the car some detail with a few stickers, including a license plate.
In robot mode Prowl received several accent stickers for his legs. They were a bit of a pain to put on since they were cut so thin, but once applied he looked much better. I did have some issues with the silver foil stickers staying in place on the top of his feet, but the others applied just fine.
Hasbro often does a good job at repurposing a mold into another character. This is one of those cases however where a little more detail helped this figure tremendously.
