おしまい {oshimai} vs おわり {owari}


Are there any differences between using おしまい {oshimai} and おわり {owari} to mean
"the end" (both with neutral and negative connotations)? Are they always
interchangeable?

E.g:

> テスト失敗したらおわりだぜ。
>
> テスト失敗したらおしまいだぜ。




I don't think there's really much difference in meaning or connotation,
although おしまい sounds more formal to me, probably because it has the honorific
お attached. OTOH, I've never seen お仕舞い at the end of a movie, so maybe there
are differences in customary usage. {EDIT: The following is inaccurate: 終わる is
also used transitively} One difference is that you can "おしまいにする" something,
whereas you can't "おわりにする" things, because of the transitive/intransitive
pairing 終える/終わる.(END EDIT, see comments)

In your example sentences (incidentally, you need to stick a "に" in them), I
don't think there's a dime's worth of difference between the two. They both
mean "I'm done for, it's all over, the jig is up, put a fork in me, Goodnight
Irene."
