Pushing what we've got, more and more; working our way around the neck with the aim of piercing through.
One of the most important principles in carving is to 'work the form into the space'.
In other words: Don't just attack the wood where you think the hole will be. Holes can be quite corrosive if approached like this, tending to end up far bigger than you wanted - and we don't want a new species of swan with a spindly neck!
So, feel for the form in the wood underneath your gouge and bring it round. The 'hole' will take care of itself.
