Quite good
I would recommend you better kick sample. This one's pretty weak for Uplifting and Classic Trance. I would use this one to Minimal House or whatever Progressive like. Anyway, the sound isn't so bad, but there's still that black space wich can be filled with percussion, plucks and other stuff like that. Changing the bass is another thing I don't hear here. The same thing over and over again... getting little boring.
Here are some suggestions for you:
Get Vengeance Essential sound sets. These will get you started pretty much.
Get Izotope Ozone 3. The BEST thing you can use for mastering you mix. I use it too. Instead of Ozone 3 you can use also Maximus in new FL Studio. You can ask me whatever you need via PM. Take care

PS: Listen to ASOT show, to know what's going on in Trance world. This sounds quite oldschool aswell.
