Not quite sure what to think of this. I like the tune, but it's a tad too repetitive; realizing it's a loop, however, I'll ignore that fact (though it's best to consider variety in the future). Some FX's here and there would do the loop some good, and additional hi-hats as well. I've lurked at your profile and see that you use "garbageband" to make your music. All is well with that fact, I'm not one to judge how one should make their music, but if you're interested in taking a more technological turn with music production I'd highly recommend FL Studio (shun me if I'm repeating pre-existing knowledge).
Also, for the sake of giving additional feedback to this project (as well as a conclusion to my review), personally I think you've got an interesting melody. It could use some extra layers of sounds and patterns in order to yield the melody to its utmost capabilities, but for someone who I assume is new to music production it's a solid start.
These are my personal opinions, though I advise you to take what I say into consideration, for future reference. Good luck on this.
I just thought of the melody today. I just wanted to get it out to the public. Thanks for the advice I have no midi controllers or just my keyboard and mouse. Is FL studio for mac?
