Now, I generally like your work. Your songs are catchy, fun, and easy to like (at least, if you like trance music). My main issue with this is that it feels like all of your other works. Yes, the piano's a cool instrument in trance; you've shown us that. But when you use it in 20 million songs, the effect starts to wear off.
Basically, what I'm trying to say is that you should mix it up a little. Use new instruments, branch out into other styles of music, and just generally mix it up a little. In other words, be original.
