Oooooh nooooo, it certainly doesn't look like that to me! With the title of your comic I always read it like, "ahhh! It's a pesky monster! This job is too much, I need a raise." I really like this thumb, though, it's one of my favorites that I've seen! The contrasting colors and values are really eye-catching. And it just looks like a fun story.
Anyways, one thing I've noticed (but perhaps underutilized) is that my eyes are always drawn very strongly to a face. If the thumb just has a face in it, I notice it instantly. However, there are SO MANY thumbs with faces that unless it's a very interesting face, I tend to click on something else. (usually thumbs that have two or more characters and thereby imply character relationships)
I also notice thumbs with words on them, but they repel me, haha. Thumbs with only words are especially infuriating to my to my eyes.
Here're my thumbnails, neither of which are particularly strong thumb compositions in my opinion. But they're fun and that's pretty much what matters to me at this point!
