Yoooooooo,
Remember that mix , most of all is about volume , don't try to over do it compress everything etc , it's kinda over rated , try to adjust volume first and when you'll be happy with the volume you'll see a HUGE différence , then try to eq thing gently by doing substractive eq , then if you're not that happy try to compress Groups gently and it will immediatly sounds proper.
But remember one thing you can't eq a sound wich is already bad from the begining , you can't make miracle with a synth wich is already not good , try picking some other synth that will fit better etc
Try also working with reverb etc to get space and depth in your mix but don't over do it 3-4 different reverbs is enough
Hope I helped !
