Things to NEVER say to an artist. This is so accurate. Should include: "Can you draw this [character] for me?" "Do you draw anime?" "Ooh, is that...?" and "Did you draw that from sketch or from references?"
I mean, eyes are easy, right? Just a circle inside a circle inside a football. It's not like each one has six different muscles and can convey everything from all known emotions down to the poetic soul. No reason for them to be hard to draw.
