nice dark trance feel to the sounds , defo need EQ and mastering as you say !

melody note work works well , no clashes

vocals would work well if they are FX'd well and only a small few , in breaks and build ups , i personally wanted a vocal , but its entirely up to you , works without but i reckon it would work with , depending on vocal choice

nice structure , nice little trance track 6/10 ;)
