Fragile is the name of the game for detail fretwork. It will be stronger and more stable when you attach a packer. I also, while scrolling, if I have a real fragile area, turn the piece over and put a drop or two of medium CA glue (Super Glue) on that spot. Let it soak in a little and them spray with activator.
You did a great job on that pattern, I did it just before Christmas. It was fun.
