Hey Marco -
I think it started out fantastic and you used different samples and rhythmic textures very well to make it interesting, Somewhere around 5/8ths of the way through it started sounding repetitive to me, and almost like playing the parts at the same time on a keyboard with really good samples.
If this was used for a suspenseful film sequence it would work great. The constant rhythm would keep the feel without distracting the audience away. So, my comment about repetition is only my opinion, from listening to it on it's own, I like the ideas, articulations and variation in your samples and rhythms. I guess if it wasn't for that one repeating section I would love the whole thing!
Good work
