I love this type happy, melodic type of music (trying make something similar myself), so I like a lot of the ideas, and the general feel of the track you have so far.
Although it sounds a bit hollow to me. Making the bass a bit more prominent could help with this and could fill the track up a little bit more, so to speak. A slap bass type of sound could work really well in this, like what Wave Racer does in the song Flash Drive (linked below, listen to 1:32 and on to know what type of sound I mean).
