Kind of has an industrial slight feel to it but for the most part it has a very nice atmosphere to it. Possibly a theme for the Everfree Forest maybe when you are nearing it and getting ready to enter maybe? Very nicely done though for that much anyways. I would not mind hearing a full version of this anyways? Was this in ableton or garageband?
The drums and claps make for a nice combination and the slight echo effect on some hits gives a nice feel of going somewhere far off and maybe never being able to turn back as the forest engulfs your personality and your mind becomes twisted with the thoughts that no one cares for you anymore and thus a spark of Nightmare Moon that was left comes and slowly begins to take over your body and mind corrupting your thoughts to where you can no longer think clearly.
The The synth gives a slight feeling of hope though that as she takes over your mind and slowly morphs you into something weird looking being your mind but your body overcome with darkness that you may still have people who care for you. Hearing that Nightmare Moon has returned the Mane six coming looking for her unaware it is only you but you fight them unaware that Nightmare Moon is controlling you and twisting your thoughts. The bass gives a soothing feeling too.
Overall, I like it, would love to hear a full version soon. ^_^
