Well mate, myspace sample quality is so kaka it`s hard to feedback effectively.
Also, this is hardstyle/trance?, so probably not the best forum to post for feedback in.

I`ll give very brief feedback, as it`s for 4 tunes, rather than 1 specific.

I`m not a fan of this type of music at all, so I`ll spare you my opinions on the style and composition of each tune.

Production wise, as far as I can make out, this all sounds a little too crunchy and digital, and could do with a lot of work to give the mixes life and interesting dynamics.
