I really like your melodies, they are catchy and really sweet! =)
Really nice chords and great use of sound texture as well!
Only thing I could really say is just varying the drum beat a little for different sections, like at 3:01, I could really hear a double time drum and bass type thing happening under the melody.
Overall it's awesome, keep it up! =)
P.S. Can't get over that piano melody, so catchy!
