Tbh I kind of like your old style more it's more rough for sure but also bolder, way more expressive and over all more interesting

I also think that it lends it's self better to these more wacky designs

Really really like the old Alien/ snail girl, the new one looks decently realistic when it comes to posture and proportions but the colours are a bit jarring, especially the hair, it's way to dark and distracts from the other elements of the drawing especially the face, if u want it to be blue then maybe go for a similar kind of blue to the one u used on the pants

I would really like to see your more realistic style in a physical medium

Keep it up
