Nice one
To be honest my first reaction to hearing this was "stolen", but that's not the case because you're music is reliably yours and shows that you are capable of making this. Which means that is a very large compliment.
Excellent job, but I would suggest using samples with a greater frequency range. I noticed that the majority of this piece had a very small frequency window. You'll notice in my music, especially my latest, that there is alot of variance in frequencies.
Regardless of my personal tendencies, this is very well done, congratulations. 5/5 Make more,
