hollowing out the front and the back

Still working with the gouges. My right hand wrist is getting sour from this work.
On top the back being roughed out. The little holes are drilled with stop, so that I have a thickness of 5mm when I reach the bottom of those holes. Later on the back will be taken down to 2,5 - 4,5mm.
Below the front at 5mm thicmness. It will be taken down to 2,4 - 3,7mm
