To be honest I like how this piece starts out with the subtle and soft piano and chorus coming in as soft starters. Almost as if you had finished the fight for your life and watching pink cherry blossoms fall from the sky. Then the drums come in and you start running back to your home with your giant sword in hand smiling.
The piano sounds very cheerful and gives the feeling as if happiness was rushing through your veins and head at the same time. The chorus synth in the background kind of gives a feeling as if everything will be alright and peaceful once more.
The drums are pretty sweet here as they pay really fast. I am going to take a guess that you played them through a couple of times, chose one you liked it, looped it, then sped up the tempo of them to give a faster punk hero feel to them.
Enjoyed that breakdown near 2:35 with the drums going up and down on the reverb for a few moments. The song is really great sounding though.
Overall, very cool victory song. I can also see it being used as a level song for those reaching the final level which is a deep space facility where the boss causing lots of destruction awaits. Excellent work here.
