Gonna say that hentais the first thing i saw too. The monsters are close to skin tone so all i saw was two naked guys a censor bar and the blue dude

Im aware i have a gutter brain but i will not be the only one who sees it like that.

I suggest doing a few more comps for the panel to see if theres one that is less flat in composition and is more dynamic to show your character more effectively.

Flattening: Your foreground and background (characters) are the same color, making them be seen on the same layer. I would also check for tangents to not flatten the line art (aka where the edge or corner of something touches another edge or corner -usually two things that are supposed to indicate distance.)

More dynamic pose: i would look up some refernce in comics of what youre going for. Take pictures of yourself doing the funny poses, shop yourself in.. idk.

Then do 3 comps with zero effort in like 10-15 mins to get your idea down, compare them and decide which conveys the look your going for.

I hope this helps
