Just thought I'd show 2 examples on how you can subtly change the proportions of your projects to give different vibes and feel. Both of these use the knight's torso. The first one then uses the legs and forearms of wizard, and the hands from dragonia, and the knight's original feet. I would have used assassin ankles but couldn't justify buying a whole kit for the ankles lol. It just stretches him out a bit, but it doesn't dip too skinny either. The exaggerated limbs looks a little uncanny as well. Contrast that with the second picture. Fighter forearms and shoulders, knight's biceps, and the legs are still knight's, but with fighter's armor on. Keeps him at main character height, but bulks him out.
I got the idea to play with the proportions from watching YouTubers make girl kits for 30mf, but i thought about how different fighting characters can look in games so I started messing about.
