Low pads and 808 clashing on some frequencies and it makes my perfectionist ears uncomfortable. You may low cut these pad ******* and maybe add some middle to them. Or you can change the arrangement so pads would fit 808s. Strings are too loud to my taste or maybe that is the string sample I don't dig, there are much clean sounding strings out there, like almost any kontakt library. Kick is tight but snare is little weak, it needs layering for some punch or like click or clack of some sort. I would also add some light part to a song for contrast, to add some contrast. Like prebuild for a chorus, which can be a string part. Because now I can't tell if there is verse and a chorus. Now it is a one solid verchorus or cherse. And you can add brightness to a high synth(not the bell one but that accordeon like 8 bit kinda of synth).
