I couldn’t look away as I was allured by the blossomy valley. (This is the first time I've ever seen the adjective form of "blossom"! I've never seen the word "blossomy" before.) A young actress craved recognition and glory.

I don’t think you can use “allure” as in 2. His calm, deep voice was alluring (to me). The allure of his calm, deep voice .... (made me forget that he was an evil man.) I couldn’t look away from the alluring valley filled with flowers in bloom. I think “allure” is more natural as a noun or adjective than a verb.

It's ok, but as a native english speaker I'm not sure I've ever heard the word "allured" in conversation... it means to tempt or lure but it's pretty much only used in books. People would just say: "His calm deep voice drew me in" or "I was attracted to his calm deep voice". Also for #3 it would be better to say "The young actress craved recognition and glory" or "The young actress had a craving for recognition and glory" but using "...craved for the..." sounds awkward.
