Damn, your right... I just reread the comic and they do progressively get bigger with each page...
I can see larger eyebrows as being more expressive and a unique art-style choice but at this rate he's not going to have any forehead area left to work with. They're already taking up like half the total space...
His character Bea from bending Bars had big eyebrows that were kinda cute and more emotive but there's a limit to that kind of exaggeration.
