Oversettelse - Spansk-Engelsk - Amor Sincero

I noticed a few things that I think could make this sound more natural, or slightly more accurate. Feel free to disregard my remarks if you think it disrupts the poetry

- se acabó - is finished, not finishes
- I warm myself in you
- the light of dawn
- for you arrive kindling the heart
- you cause my soul to feel love anew

Hi Lein!

I agree with several of your remarks, specially the second (to add "myself" and change the preposition, even if I would choose "with" instead of "in" ); the fourth ("for" sounds better than "since" ); and the last one (this "to" was actually missing).
With regard to the first verse, that second verb should strictly be in past tense, as you note, but I like it better in present; of course, I leave it for Lilian (and you) to decide.
Your third point is good as well, and "[the] light of dawn" –maybe without the article-- could be substituted for "dawning light". I leave this also to your criterion )
Many thanks for your interest and your help!
