Why don't people notice...

I've noticed that on Fanpop and deviantART, only a few of the Bolt drawings really look like Bolt. Most of them basically (and no offense is intended!) look like white Собаки with lightning bolts on their sides with some Bolt traits. So why don't people notice how far apart Bolt's eyes are, how big his ears, eyes, and nose are, how the розовый inside his ears are, или (most importantly) how big his head is? I don't get it. Am I just еще observant than most people или something?
