Professional or amateur?

Are there any errors that would give someone away as not being a professional layout artist?
An amateur is likely to use more fonts or more decorative fonts or apply embellishments like shadows and outlines. An amateur is likelier to put borders around things. An amateur is likelier to even out the “gray,” making the page elements similar in size and spacing. From a pro you’re likelier to see very bold moves and high contrasts of color, size and position.
