Squink's new resin headed Dunny or simply a custom for ToyConUK?

Clik here to view.We love showing off the immaculate sculpting work of Squink, but this piece feels different from his normal work to me for some reason. In the light of the fact that he's recently decided to retire his resin cast head custom Dunnys, I strangely feel like this might be the new head sculpt he'll be casting. Now, in all fairness, we do know he's planning a new resin head Dunny design, though he's marked the above one as being for ToyConUK… so it might be just a custom or he might be debuting the new head sculpt at ToyCon. What do you think?
