If Odo was found by the Bajorans surely he would try to replicate their wrinkled noses rather than a more human appearance. I don't know why this has started bugging me today.

I agree. Also, it always seemed strange to me that he could replicate objects so precisely that no-one could tell, but was unable to manage a face. Why not???

Quite. And yet the other changelings could when they wanted to infiltrate the Romulans, Klingons etc
