I love your cartoon and the style you've done it in. Last week I didn't know what to say about it until @Jesper Axelsson pointed out the visual effect with the mouth being open or closed. Now I see it. I think his addition of teeth would be a great idea. Other than that, great job!
@Liandro Haha😂👍So funny! - In the close up of the dentist my brain got a little confused; for a second it read as if his mouth was closed and that the upper lip was the cheek bulging up from the smile. Maybe adding teeth could help clarify the read of an opened mouth. Cheers!
Oh crap, I'm never seeing my dentist the same again :'D Wonderful line flow and courbe dynamics !
