school help: Next period I have critiquing with an extremely scary teacher. - Help.com

Tell her Halloween is over and to quit being scary.

No one has the right to be so critical when you have taken so much time and effort over something - she sounds like a horrible woman with no life outside school. Ignore her critisism - it means nothing and she is clearly compensating for a lack of a social life (she gives you a brutal critique, you give her a critique on her life ;))
Good luck :)

be honest with her, that it took you that amount of time and youre not sure how to improve it, but you worked your **** off.
if shes any kind of teacher, she will appreciate the amount of work you have put in and help.
if all she critiques is how crap it is (or isnt), then shes just on a power trip tryin to make herself feel cool and you can just ignore everything she says.
