Pretty good
For musicianship I give you an A. B for originality, I could tell it was original. But it didn't flow into different moods, basically it wasn't a "complete" song (intro, body, climax, conclusion) in my opinion, . Not that it wasn't good, It is a lot better than a lot of stuff I hear on this site. I can be a tough rater since I am a songwriter myself and believe me I'm a lot tougher on myself than anyone!
Overall a good song, I like the style and the sound was good.
Good work.
