Sounds very nice and clear. No strange skips you might hear in other things. In general, it's perfect. Just gets a little repetetive at some parts.
an uplifting tune
This really reminded me of that pop song - 'All Together Now'. At least for the start anyway, before you changed the lead melody.
When you got away from that, I started enjoying the tune for what it was and found that whilst it could have a bit more diversity at some points, specially in the lead melody, it made for a good background piece.
I liked how you mixed up the beats and various bg layers though and liked the soft melody around the 2:24 mark. That was maybe my favourite bit and I kinda wish you'd kept that particular layer going a bit longer.
Anyway, it was generally an uplifting tune and commend all the production work on this.
