Hapy music
sometimes its nice just to stick some interesting sounds into a well known chord progression, and just make a nice sounding song. And this does exactly that. Theres some nice mastering here as well, you can hear the extra effort thats gone in. The piano is a nice little touch, gives it more of a happy hardcore vibe.
A little hint, if you want to make a really upbeat soft piano part, add a load of reverb, then put it over a pad (look up Kaechi! Teochi! Yoshi! by Yoshi J and you'll really see what i mean).
Looking at your stuff your very good at setting a good vibe for a song, the only thing i can say to think of is the actual melody, though they are good, i still haven't heard one i thought was special. Not trying to be too critical because mine are no better, aha, just the area i feel you need work on to start turning out some really top of the range songs.
Anyway, i really enjoyed that, glad i had a listen :)
And keep it up! :) haha
