nice pads :) there's a bit of clipping here and there - it probably comes from one (or several) synth that has several OSCs turned on and/or its resonance above 0%
you can counterbalance that by turning down either the general volume knob of the synth, or the volume knobs of its OSCs
Personally, I'm a perfectionist when it comes to the loudness of certain elements in a track and I think you could use a quantum, gravity or compressor to lower the sound a bit for some parts of the track.
