It was a okay piece. From the beginning to about 0:55 sounds off. The notes you've chosen just don't work well. Harmonically speaking its almost random at best. What I think would work better is taking your main theme and having your bass line play it at the beginning. Overall you have some really good ideas, but they just don't fit too well together. Another example is the melody that starts at 0:55. That is quite nice, but the bass sounds really bad. Maybe use pizzicato instead of those really harsh marcato notes. There are several other places where the articulations you chosen just don't seem to fit in. You have some mixing issues as well. There is almost no dynamic contrast and if you had them they could easily make your piece sounds a hundred times better despite the issues I mention earlier. Although these are my opinions and not the rule, I think they could really make this piece something special.

Really calming and soothing at the start, then it gets more energetic near the end of the song. Sounds like something you would hear from a great composer.
