Great concept, nice joke but I feel like you could improve in emotions. Both on the animation and the voice acting (though your voice acting is good already!). I suggest exaggerating emotions a bit more like, when the detective 'freaks out' he shows mid emotion, just like he saw something that's not ordinary but not that 'WOW HOLY SHIT WTF WAS THAT?!'. First of all, you have to think; what would a 'normal' person do when some kiddo randomly spins and levitates away? They would be losing their shit! You could draw the person in question like they just saw the most life changing, mind scarring thing ever. (I'm not good at words and I'll gladly draw a tutorial, though I'm not a professional :P) When the guy questions what the fuck did Ash just say he acts like it was just a drunk guy that said a sentence in the wrong order, he, instead, could to be all like 'what the fuck are you talkin' about?!'. When the expression are exaggerated, the animation gets funnier.
I really hope to see more of your works!!!
