11 reviews in 2 days? O_O Wow...
That's a lot of reviews for 2 days of being in the Portal... I've barely achieved that rate of reviews, and then that's with my latest song, Nova. =P You must really want reviews for these two. Here's mine, then. =P
This song does sound like a "light mix" of your previous. And a good one, at that. It's definitely better, and very uplifting. Melodic, too. You've set up a good (though somewhat cliched) attitude with this.
Your introduction is nice, as are your transitions. Your ending is a bit abrupt, but is decent nevertheless.
Your choices in instruments are good, especially the piano. The one exception to this would be the loud, standout, snare-like drum you introduce partially through the song which fits but not to the same degree as everything else. Other than that, it's overall a good submission. Quite the party song, too. =P Keep submitting - PM me if you ever have something you want me to review. =)
