I like the jazz, improv-y quality of the track and the sort of sudden explosions (I guess the thunder strikes hehe). I will say that I would also appreciate a few more "sign posts" so that the track has more shape. I do notice some repeated motives (the descending chords for the thunderstrikes, the chromatic lines up top), but maybe a bit more dynamic contrast could generate more direction. From an audio production standpoint, I feel like it could do with just a tad of reverb, probably a small (smoky) room. Good job!
