Could you check my writing, please?

I want them to sound very polite! Could you check my wrting for grammar and vocabulary, please? Thakn you.

I've listen to the song and read its lyrics, and for practice I tried to translate into Spanish to match with English rhymes. It is not so hard for me to translate it for just the meaning of the words like I interpret it, actually it's easy, but it is a quite hard task to match rhymes with the English version!
