Cool
The bass synth is awesome. The only really terrible thing I find wrong with it is a few note discrepancies and the string synths, which chopped up the flow of the song. The piano and bass part around 2:00-ish was soothing though, and that makes up for it. Some EQ would be nice though. It is pretty static-y, nothing I can't put up with though.
As for throwing the rhythm off, no, it's perfectly fine. I definitely think I like your later songs better though, which is a good thing, since it means you've improved. Good work!
