Rest In Peace. You will be missed

Rest In Peace <3

I understand this is a different genre than I usually deal with so take it with a grain of salt, but I would move the first "blast off" to just before that quiet phase when piano comes in. Dramatic effect. The incoming piano would make it sound like you are actually sending something off into distance as opposed to just capping off a buildup. As far as the melody... I come from the school of thought that it trumps all, so I am not too enthused by the repetition, but I do recognize that it is widely acceptable within dance/trance genres. I would also say that the compression (I am more or less assuming that is what is causing this) is making this a constantly near volume limit spectacle - keep in mind that will distort sound and make it hard to listen to at times. Otherwise not too shabby. I do think you have taken some of the things I have said in the past into account :)
On a broader scale, be brave - do not stick with just one simple melody leading the whole tune; use variations, use different melodies intertwined and other little tricks to make the piece cohesive, longer and more rich in interesting bits. Yeah, learning some music theory if you do not know any WILL help. If you know some, go back and dust it off. I keep going back and trying things from the basics every now and then only to find out I have so much more to learn T_T xD

Cheers, and keep going!
