Well, text, like any other thing in a sig montage, needs to have a purpose. The way I look at thi,s the text could either stand appart of the main render/focale point, and stand out from the rest to create a contrast between the render and the font. It makes the font easily readable (if that's the goal) and it balances everything else. However, if you want the text to be part of the sig as a whole, and be complementary to the render/focal point, you need to make another style of font to get along the render. Like any other effect, the font would compliment the whole thing and the art style.
Your font is none of those, as the font doesn't stand out enough to make a contrast between the render and the text, nor is complimentary to the render, as it interfere with the art style you went with.
It happen most of the time when the font was placed at the end of the process (the sig), which I don't know if it was your case or not, but that's what I meant when I said it felt out of place.
