Walnut progress

After a lengthy bout of lack of self motivation, today I picked up my walnut carving and began working on it again. Forgive the lighting. I left it a bit late to photograph. 
The hole in the front of the carving will hopefully have a piece of Jade/Nephrite inserted. The hole in the back is for natural light to shine through to enhance the variations in the greenstone, I hope. I still need to shape the semi-circles and add a v-groove design before I focus on sanding and staining.
The hole below looks off-center but I think that's more to do with the illusion created by the smaller hole along with the angle I took the photograph.

Walnut carving

Here are a couple of photo's of my newest carving I'm working on. I'm unsure of a title yet but am aiming somewhere in the region of 'Hazardous Waste', Radioactive.....?. You get the general idea. 
I have found that this piece of wood (walnut) has a lovely grain to it. I think this is due to me previously using driftwood which doesn't show the grain as well due to being submerged in water for long periods.  I'm only about half way to finishing this piece so still a bit of work to do. The back (top below) was a challenge to add a curve to it but it's either beginners luck, which probably means i'll never be able to do it again, or I might be a natural (lol).
