Hello Fernando,
It's hard to tell on the top - it almost looks more like Spanish Cedar (sounds great, BTW - smooth & warm).
While there is more than one wood using the "Kingwood" name, what you have looks like what I usually call Kingwood as well. It's a rosewood, gorgeous as is yours, and the tree (almost more of a shrub) is so small, and with such a poor heart condition, that you need to use a lot of sap. The heart is just never very wide. Rafael's come up with some intersting ways to deal with that situation. Very well done!
We've got some "little bitty" rosewoods in our area that fall into the same category and I'm really tempted to start using them. Has Rafael worked often with Kingwood? It appears he's using it for the neck as well (or is that Pau Ferro?). While we're at it - what about the fingerboard?
Congratualtions - this should be very nice! Looking forward to some sound. Thanks for posting the pictures.
p.s: if Rafael knows the Latin names, I can tell you for sure.
