A good start.
Not too bad, especially for a first piece.
I only have two major complaints. First, at ~1:15, the drop-like sound is very... Not quite sure what word would be good there. They don't sound quite right, though. They are very out-of-place in the song. I think if the instrument used was matched more closely with the rest of the instruments and tones used, the notes would fit much better.
Otherwise, the only other complaint is the sudden end. It almost sounds like you had intended for it to go on for a couple more notes, but accidentally cut the ending off in the post-processing phase.
Anyway, not too bad. A very, very good start!
