Drawing of Final Project

My initial idea was to do a hair pin or a pendant. Below is the first sketch that came to mind, I feel like I need to add more or refine it more. I want to make this pendant out of silver, so currently I am trying to carve out of wax, though it seems to be quite difficult to make 1mm - 5mm size sea grapes by just carving them, so I was thinking of doing droplets of wax might work better then sanding them so they are not quite as rough, for the big ones, I'm trying to hollow them out. so that in the end they do not weigh as much.
