This is the fourth track you've ever composed?? Damn, my fourth track was absolutely nothing like this. It took me a year before I could make anything in the same realm as this. Good work! If I had to give any feedback, it's that the main lead somewhat stands out against the resonating pads/synths, due to it's lack of reverb and the like. I would add some reverb or something, but honestly, even that is just an opinionated criticism, I could totally see keeping it the way it is for a reason. Overall, great job! If this is your fourth track, I can only imagine what you can do with a DAW that isn't Garage Band!
