How do you tell differences between traditional hand drawing

The distinction is virtually almost entirely in skill/familiarity alone. Unless there's something particularly aberrant in digital drawings (photograph filter artifacts, distinctively digital objects, impossibly perfect replication), it tends to be a very slight distinction.

The one thing that I have noticed, which tends to be the first failing of most artists switching to digital, is a certain loss of perspective and crowding. Why that may be is anyone's guess. As I said, though - this distinction alone exists because of a lack of skill with the digital tools. As an artist grows more accustomed to the digital tools, this issue may or may not become less prevalent in their art. If it does become less prevalent, the veteran reader nonetheless retains the knowledge that the art is drawn digitally. This does not mean that they can actually tell the difference 10 out of 10 times in such a circumstance, though; it merely means that they might be more wary of aberrance.

You have to be born with the superior sex so I'm afraid you will have to wait until you reincarnate as it.
