Gah, that sort of criticism goes with the "never use adverbs" which some writers (naming no names, but a certain Horror writer with a royal surname springs to mind) try to push. Oh, and together with certain forms of Political Correctness which not only ban ever mentioning any differences of coloured skin but also want to ban the actual words for colour (nope, can't call then blackbirds any more!).

In re. the eyes, those people have probably never looked at the eyes of real people. Or they are colour-blind...

And in re. the "Mary Sue" accusation, I suspect that they have no idea what a "Mary Sue" story is. It's specifically for stories where the author inserts themself as a thinly disguised main character as 'wish-fulfillment' ("Oh, I really want to meet Spock, I'll write a story in which I meet him and change my name to something generic"), nothing to do with over-use of inaccurate adjectives (which has afflicted some professional writers no one ever accused of being "Mary Sue").

Ooh! Just noticed a progress meter for "Mouse and Dragon"! Yay!
