Lol, your models

do what makes you happy with em.
Rule of cool

if they look cool then its all good
Deadmau5 is not a dubstep producer though

he does house
afaik.
I can imagine that Excisions album art and promo posters are the style your after. But there is no general theme across the board for dubstep album covers, or vinyl sleeves
tbh... everyone does it differently, uses different colours, themes and styles.
I wouldnt go around saying that youve got dubstep marines ora anything, becasue someone who is actually into dubstep, and has been since the beginning of it (like me) will call you out on that crap), Dubsteps been going since early 2000's, skrillex is a very late comer to the scene, the pioneers for it were skream, benga, artwork,
El-B, horsepower productions, DMZ, caspa & Rusko etc etc...
Lables to consider looking at art work for might be Dubpolice, Tempa, Audio Phreaks, Argon, Bar9, Hollow poiont, etc etc etc.. theres countless labels that publish dubstep music and theyre all a bit different in style of art and sounds.
