To me it sounds like a happy techno song (that happy hardcore trance stuff.) Maybe add some near high note catchy melodies. For melodic helpness i suggest sticking with the white keys since those are the ones that sound more happy in a sense. Maybe play around with CEFG and then another C another octave higher. (just play around with a CEFGC note pattern.) Its turning out to sound pretty good.
Try to pull in something lighter that builds up?
Please contact me if you would like to use this in a project. We can discuss the details.
