I enjoy the concept very much, reimagining standard characters is always a good idea! The current, pot-belly pear-shape of the body and the additional human elements seem to hamper
the likeness overall, though. The same quite applies to the palette you're utilizing, it's a fine selection of colour in my mind but doesn't quite convey "Pacman". Maybe you could try utilizing the existing double chin (which is a great idea!) in a manner that would make his shape seem more familiar, for instance by positioning it lower and thus enlarging the mouth as well?
