"Good...but...."
Good melody, I like it. It seems rushed though, especially through that little piano part around 00:50.
I'd slow it down a few beats, boost up the bass, and really focus on those accents in the background: like the thunder, for example, put a lot more bass into that, and really make it stand out, it's a great addition to the beat.
Also, I'd like to hear BOTH the synths (main melody) play at the same sound level (especially at 00:30!).
Good job!
