It's that the same artist that did the Drrr Drrr Drrr story?

I'm not familiar, is that another comic?

Yes! That's the one.

Here's the comic. a little different than i described it but still very off putting

thanks for the assist

There is a collection of black and white comics which depict something very similar: There is a boy looking out his balcony with a telescope(?) and notices a monster or demon off in the distance.

The frame in which the demon notices him back gives me the same awful feeling in the pit of my stomach that this gif does at that moment. If I think of the comic I'll edit it in

edit: Here it is. Thanks to u/blamezuey for helping to dig it up
