This sounds like a garden theme, or a forest theme. It sounds more like a garden theme to me though. =)
1. Um...wow, I cannot tell the time signature. The way this is composed makes it really hard to figure out the time signature. This hardly ever happens. This is like one of the first things I try to figure out during a song, but this one has bested me....If I were to guess, it's in 4/4 time with a pick up note in the beginning to throw me off. If that's right, I win!
2. I like the drum beat.
3. 1:27 part. I like that you dropped the main string of that part. This is something I should practice more instead of adding more things to a song.
My problems with this song:
1. Hmm, the mixing needs a little tweaking. The main string that I was talking about earlier is a bit too loud.
2. This could use a a bit more changes in it that are less subtle. Maybe like changing the pitch, or rhythm or something. If not that, maybe by changing the drumbeat.
overall, this is a unique that I'm not sure about the time signature. Just the mixing needs work, and more changes are needed.
Keep it up.
