Very nice. I think you have to layer the drop chords with something brighter and wider. I usually have that kind of base chords like you have and then put a sylenth supersaw (with some whitenoise sometimes) to brighen it up and make it more full. Route those two layers together and multiband compress them.
Yeh. My mixing has been kinda bad lately... Could be because of the headphones I'm using... But I don't wanna use too many Johns.
Also I'm working on a Splatoon credits remix. Trying to go for an 80s/retro feel...
