Just simple things like compression,subtractive eqing,panning,reverb,delay,bit crushing and distortion work well for me just try to be subtle with it,try not to go over the top.
Just try to eq everything around one another by taking frequencys out of things that dont need them and panning elements around creativley,like I say simple but works for me.
Theres other people on here that could help better than me tho.

Try asking in the production forum how to get more dynamics out of your music.
Hopfully some of the more clued up peeps can help.
