Pretty good piece in terms of concept except for a few kinks. what you really need to work on is getting that bass thumpin out there, along with mixing up your layers a little better so they blend.
Aside from that, the piece is kinda disjointed, like the beginning is way too different from the end. Since it is a trance piece, itd be better to try to stick to a main melody line like the beginning had with the happy ticklish noises. You kinda lose it at 1:04 and onward, i mean its okay to deviate a little from the main melody for flavor but you always want to come back to it so the listener isnt lost. But yea the beginning is great =] i really like the theme tickle, hee hee.
