historia de un amor vs piano

Hello everybody, I hope everything goes well for you. This is a great first for me ... I had arranged this superb song for voice and orchestra in 2019 and several times I was asked for a version for solo piano. So I embarked on the adventure and I did as I thought ... I hope that my version is playable without too much difficulty ... The little entry I made is completely optional. You can start at bar 10 .... I need your advice because I am often asked for a piano version of the orchestrations I post. I remind you I am a saxophonist and not a pianist, I need your opinion to progress. Thank you in advance
