Quiet mixes from Studio One

I wonder if anyone can advise where I'm going wrong?
Studio One reports "Clipping has occurred 0.5dB over" but the mix is very quiet compared to most.
This one for example.

Thanks in advance. :)

I once had similar problems in Samplitude without knowing why. I loaded your track into Expose. In the setting "MasteringSoundcloud" it shows two red areas from about 0.58s onwards. Peak - Decibel True Peak and Decibel Peak 0.23dBTP and -0.00db and in the dynamic range 1.5 LU
Have fun searching :)
