There are some cool ideas in this mix, its kinda minimal in soundscape however. The synths are somwhat generic, and the lead sounds bland, but there is something quite appealing about the sound you have, its just not quite meshing together quite yet... That clap sample is rather thin, i'd try layering different claps together and adding a small amount of reverb to boost it up a little. The synths have alot of reverb and delay added, which gives the track a very spacious sound, but I feel like it never reaches its full potential... it sounds like there is a missing frequency range somewhere, I'd try adding some sort of rhythmic synth in the most dynamically full sections to increase the fullness of the sound and add more interest in the mix. The lack of a download link is annoying as without it I can't pinpoint with too much ease where certain issues are... for example, the 16th notes in the bridge section after the main lead part have back feedback timing which causes the notes to bleed into each other.
As for the arrangement, atm, it sounds too repetitive, you need to change things up more add some more countermelodies and solos etc... altho from the sounds of it you intend to do just this, and there is alot of dynamic variety, altho there might be too many change ups...
Well the good points are that you do have some variations on the main theme, the sound design while not awesome is commendable (the synth that plays the main riff is sweet).
I'd keep working on this one, it shows potential, good luck!
