So... the font is legible. It just looks "bold" and that takes away its crispness. If there's a thinner version of the font, that will be better. The largest problem I see is with the "t" letter and spacing between it and others - the largest being it looks characteristically identical to a lower case "L" or the side of the lower case "H". So in the word "the" it looks like "lhe" not "the".
Alternatively you could keep the font, but you'd have to manually space the letters out so that they remain clear, or find a way to modify at least the lower case "t" to be readible. The font also looks... weighted and heavy? so I'm not sure what kind of comic you're wanting to go for, but it's clearly a "specific kind".
This is an article that talks about the importance of font and variance and stuff. I figured you might find it interesting since it's a relatively 'regular' comic font being used in different ways across a single page.
