Hey man, don't be so hard on yourself just because you're experiencing a momentary lack of creativity. Keep in mind the 'momentary' part and let go of the feeling keeping you down. You can't just make inspiration happen and rushing it makes things just worse. Instead you should use the spare time to fulfill other areas of your life. There you'll find new inspiration derived from newer experiences had in the meantime doing something else. You never know what can happen in life and strike your creative bone. Being open is the key because just as everything in life and the universe is a cycle and a phase so is your lack of new ideas. You're probably just tired and overburned. Aknowledging that this is just a phase is the key to not let it bother you. Acceptance opens the doors for new energies to flow and new creation to be spawned.
That said, onto the music.
The piece is much better than you think, especially compared to average NG standards. The production values are very high. The mix is excellent and the instruments coherently complement each other without any excess. Musically what I really like it's how you interwined the bass melody with the main theme. When the bass kicks in, it's harmonic play with the rest changes more than slightly (and not too much) and in a very subtle way the perception of the piece. Nice touch :D
Also your play with atmospheric samples filling in in the right moment (seems like psytrance influence - a good thing imo) with the right amout of reverb for added spaciosness that goes well in contrast to the tightness of the carrying beat. And besides that, you know, simplicity and repetitiveness are not neccessary a bad thing. I as one rolled very well with it and the music looped cca 16 times (listening while working) before I noticed.
It's a good thing you posted the song and I don't think you should go back working on it. It's here and out of your closet. Make space for new flows of ideas to come in and you'll be all set for the next phase of your creative journey.
Because I know what you're experiencing at the moment (been there, done that) my rating is completely subjective, But it's a 5/5 and 9/10 from me, and I faved you so I can keep track when you wake up from your slumber.
Once creative, 4ever creative... so you just keep on going. Cheerz (^_^)
