Anatomy of a leaf

I have been quietly carving and playing around with the depth of the leaf veins today, sanding and filing as I go. I haven’t wanted to go too deep or create undercuts in places as the surface of the stone will collect debris and water when it sits close to the ground. However, I don’t want the carving to remain flat, so I’ve been trying to simplify the junctions of the leaf veins and the midrib of the leaf. The surface also needs to be comfortable to sit on and I am keen on making the stone very tactile to the touch.
