Ahhhh....pig--ham--gotcha!
I think honest criticism will be appreciated by all. In fact, I've found most people--especially those who take their work seriously--get more upset when others just pat them on the head and say "goooood map, niiiiice map" than when they receive hoenst criticism. As long as, of course, that criticism is ever kind and friendly and heart-full, encouraging to even the worst map known to man. (I know what you mean about that harsh criticism: I was in many a creative writing rip session. Not nice, not acceptable here at the Guild at all in the least no way no how never. )
