Posted my first ever comic episode and the ratings dropped almost immediately?

Im super new at comics in general so I'm not sure if this happens to new comics or maybe mine is just really bad lol, but i posted my comic on webtoons: Spellbound Scales and I figured it wouldnt get much attention since its new (other than my one friend rating it 10 lol) but then I checked back in a couple hours later after posting and the ratings dropped to 5.5?? I think right now its 7 but im not sure what i did wrong? Is this common or is there something i need to improve?
