Some Assistance Please

Ive been working on a tech house track and just cant go anywhere with it, ive did a track with and without vox samples on this. The only reason ive placed vox samples in is well i though it had a rather commercial house sound about it, and was looking to see what it would sound like if vocals were on it.

Just looking to see what you would add or change to the track and anything you say as always is taken on board.
