That is a very beautiful bow. I like the colors on the belly!
Could you describe how you make the hollow limbs, and how you tiller such a design? In particular, what tools do you use to do so?
Its really not that hard to make a hollow limb, i used a round chisel for roughing it out and continued with a round cabinet scraper, takes some time but is well worth the effort. Tillering is mostly done on high sides.
Good luck!
