Welcome to the forum, alberto.
I like your avatar.
Thank you for sharing your recordings. I listened to the first two. I really liked the smooth jazz of the first two minutes of the first one... I wanted to be in some dark smoky nightclub holding a drink or two while listening to it.
After about the 2:10 mark it got a little discordant for my taste.
The second piece (piano solo) I really liked. It started out very minimalist in tone but then transitioned into more of a new age flair (and I love new age music), although with more interesting chord progressions than you find in most new age music. I thought the recording quality on that one was better than the first, as well.
p.s. No need to apologize for your English... you write English better than many of my (American) college students.
p.p.s. I just got back from a two-week vacation in Italy, where I was able to visit your lovely cities of Naples, Taormina, and Catania. I was overwhelmed by all the great art and ancient sites you have there as well as the friendliness and helpfulness of the people we met.
