Idk if you’re doing it for this purpose at all but “Mario’s” eyes in the body swap art are so intense with the shading, they look so sunken and hollow. I just imagine Bowser is doing absolutely nothing to maintain the health of Mario’s body. They’re gonna swap back and Mario is gonna feel so exhausted and hungry bc Bowser didn’t bother with any of that, he had more important things to do (like be a total creep)
Oh I'm so happy that someone has pointed this out! :D Okay, so here's a direct comparison:
One thing I did right away to give Bowser a more evil gaze was make the pupils a lot smaller. That's where a good portion of the intensity comes from. The size of the pupils and irises always plays a huge part in a character's overall friendliness, and it applies for both extremes.
As for the shadows and wrinkles, they make the white areas of the eyes stand out more, which tends to further accentuate that intensity. Even when he's relaxed, my Bowser indeed has those visible creases, but that's mostly because he squints a lot. He's got that typical "evil glare", if you will! 😆 Though I gotta say I love your interpretation of Bowser also neglecting Mario's body to the point where it shows! 👀 I'm definitely keeping that! 👏
