+Arianna Piantino if you allow some comments:
- after edro hin needs to be lenited (the first consonant of the word changed) because it is the object of the action, so it becomes chin
- I don't think na is needed before nin; tiro nin in itself means "watch me, lok at me"
- baw is not used to negate verbs, it is an interjection meaning No! or don't!. To negate verbs you use avo, and again the verb is lenited after it, so it becomes avo bedo

If I may comment too...
-"your eyes" would be "i chin lîn" (in+hin+lîn). "Le" is and could mean many things, but we know that it doesn't mean "your". The possessive pronoun is "lîn." Also, in Sindarin, having a possessive pronoun on it doesn't mean that "the" would be dropped as it is in English. In Sindarin, possessive pronouns are adjectives, not specifiers like they are in English.

So, a re-translation of the poem may be:
Edro i chin lîn (Open your eyes)
Tiro nin (Watch me)
Avo bedo (Don't speak)

Lovely photoshopping on that picture, BTW!

In Italian has been translated differently ..... but why? : '(

now it is right?

I don't understand what you mean. What has been translated differently?

an Italian boy has translated some phrases of the Elvish language. Probably he has made mistakes. I, that I was afraid of making a mistake, I looked at what he had written. But it was still wrong.

I see, thanks for clarifying.
