:D great job, man
You have a really good sound to this :) this is what I think.
Your sound quality is very good on here, I see no errors/bad sounding things in your samples. The synths are not groundbreaking, but there's something about them that I can't put my finger on... Its good though. :)
The arrangement of it is very nice, It all flows great. Your soft parts and loud parts transition perfectly, and you did a nice job equilizing it all. The song itself keeps its pulsing beat while maintaining an excellent melody. doododododododoo...and then you tie it up with the falling pitch/tempo. Nice. :)
You seem to have an excellent feel for music composition, it really shows. I look forward to hearing more of your stuff in the future. Keep up the good work!
