I'm too lazy to illustrate it (plus I think I'd get too caught up in the process LMFAO) but when drawing/adding personal touches to Lif's design I am channeling Lio Fotia Promare for his armor (ESP the Mad Burnish armor) Lewis Mystery Skulls (less aesthetic similarities reflected but like, kinda similar broad chested body type similar vibes and important heart motifs) (heart motif isn't pictured in this Lewis image but if you've seen the animated music vids you get it) and literally just any 2D animated Disney villain who is Shaped and Dramatic (and has a huge fucking cape or coat -- tbh the specific ones I think about are Maleficent and Cruella just from the dramatic/big cape standpoint, purely aesthetic)
(fuck it after a lot of thinking Hades is a good one too)
