Chill, relaxed, hi-dolla (:
It's definitely got the summer feeling going, dude. I like how it's relatively simple, but it's also got a nice layer of complexity to it, it gives the whole thing a really professional feel. 'Atta boy. ;D
Tone-wise, some of the synths I didn't like (the one that comes in at :50 being the only one that comes to mind ;P ), but that's just personal preference, I think, it took away a little bit of the smoothness for me.
Overall, excellent song, this is the kind of stuff that motivates me to get better at writing electronic stuff. (:
