THe beginning hihats swing too much for a trance song. Just sounds weirds in my opinion. The 303 sound and the bass do'nt go along . You should at least harmonise them if it is'nt playing the chord root. The main melody is ok till the last chord of the phrase , this one just sounds way off, too dissonant for a euphoric trance tune. The beggining sounds exactly like dj passions tune kingstons kitchen but then you add that last chord that kills the euphoric feeling.

teh bass and the kick sound nice together but it does need a tad bit of eq. Also it has a very reason ish sound. Try using some nice plugins to make it sound nicer.
