It's ok. It just doesn't seem like it reaches a particular climax. It definitely feels like we are missing what makes this piece whole. I think you should finish it because it is pretty decent. It seems like you are creating so I would like to see what your creativity can do to stretch the song further and wrap it up nicely at the end. I give it a 2.5 right now, but I think you can get it close to a 4. And don't take a 2.5 from me like it's bad or its the end. I'm just a tough grader. Regardless, I'don't still like to see the end result so I think you should definitely finish it and make it a longer song.
