You really need to shorten your intros. It takes way too long to get into the song, and it could potentially drive off any newcomers, as hearing ~30 seconds of 1 instrument doesn't exactly draw the listener in.
The violin part at 2:30 seems out of place, and also has no bassline. You were doing fine the rest of the song, but this part just seems so out of place.
That's pretty much all the criticism I have for this song. You're getting a lot better with the basslines, keep it up!
