Reply to Pads for a chillout track

I'm in the means of creating a chillout track. What I have so far are some carribean drums. Drum samples done with a MPC.
Of course some beach-atmosphere-synth and a warm sounding guitar.

It builds up slowly then I make a short break and want a passage which sounds a bit heavier. Therefore I tried to introduce some pads, but it just doesn't sound.

Any ideas what I could do ?

Btw. I use Ableton 8 Suite.
