Dr. Who took a killer mature picture too. In my experience, bulls that have been prepared for pictures or shows change a lot after they're turned out. They will all most likely look like crap for almost a year, especially if they're turned out with cows as a long yearling. But after that, the good ones will come back looking better and better for the next few years. Our bulls always hit their peak mature phenotype at about 4-6 years of age, barring any injuries or being turned out with too many cows.
