I'm a fan of happy music so appreciate another another musician who produces this stuff. As for the genre, it doesn't really matter what it is. There are already thousand of songs misplaced on the audio portal and no one really cares anymore.
I like the intro chordal pattern and the mixture of instruments that have just enough reverb and delay. The filter could have been more intricate rather than just frequency changes.
0:30 I like the climax but only for a short time. The reason is that the drums don't sound exciting enough to be in the climatic part. Also, the lead instrument doesn't really change at all till the end of the song. Surely this is a WIP? You definitely have something going on here so you should continue to make it a full song. Add some fx sounds, make the lead instrument sound a bit better or add another instrument on top. Change the drums.
Overall, I thought the best part was the buildup to the climax. There is just something uplifting about a good dose of chill instruments with reverb and delay. That heavenly fell seems to disappear at the climatic part which was a bit disappointing. Still a good attempt at making a happy song. 5/5 and finish this song.
