first one: I love that rhythm. really keeps me on my toes, that violin melody is glorious, too.
second one: creepy. the glassy sounds with the reverb.
third one: my instant favorite. Very nice voicings, harmony, and a killer catchy melody. I found myself whistling along lol.
Your tracks need actual names! Apart from this there is enough material there for a complete soundtrack in each of the three tracks. Please come back next time around and develop them some more. neat work!
