This looks almost like an Earth Wind and Fire album cover, and I freakin love it! The stars looks super nice too, however I feel like it could have more shit going on.
The '80s were a time of excess, and I feel to truly capture that feeling of excess, would be to put immense detail and a whole lot of shit onto the canvas to show that really crazy side to the cover. To be honest, this looks more like a '70s album cover, which is pretty damn good, but not '80s.
In a lot of '80s songs, note that they put reverb on literally every instrument into like, every mix ever during that period. It was pretty much the cool thing to put a shit ton of reverb on everything in pop/rock songs of that period, which really shows that everything in the '80s was more or less just excessive and overdone.
