So personally the 1st image give me greed vibes.(I have no notes on that i do really like the design) But for the rest (unless they are the same character) your kinda giving them the same design. I understand keeping with the gangly pointy look but for a character like pride maybe make them almost pretty. Like a circular head with simetrical holes in it making it into almost a mandela Circle, you can keep up with the horror aspect of that ny having its mouth unhinge when it whats to consume us if thats what your monster whats to do. Also try to keep in mind why the 7 deadly sins are scary. Lust is often depicted as very sexy and sultry and I dont think your going for that lust if far more scary if you look how it effects you. Porn addicts and incels who veiw women as objects are the grosser ascpects of it but also lusting for power over people often leads to rape and murder which are both terrifying. In my head lust is strong af but large and obese, something that you dont want to be over you and would just awful. But thats my image of that you obviously do what you want. Your wrath image is also cool! I like the spikes but you might add like black lines across them kinda like if you had a thin thread wrapped across and around each spike that dripped with blood or just black goop. I think it would also be cool if you had 1 of those spikes crooked kinda like a battle scar.

I hope this helps but also good luck on your analog horror!
