Its nice apart from the super clean edges where the wires are coming out of.
Have you thought about how it works?
The image the is currently getting conjured up in my head is of some old man painstakingly going over the holes with a file to make it curved and perfectly smooth.
I would more expect at least some cracks and a slightly muddier edge rather than the straight bevel you have at the moment.
Also the curves themselves look unatural, they dont appaer to follow the woods pattern. I know you probably did the curves first then the texture (i would have done no questions asked

) but it now doesnt look right.
You have also covered up the nice painting you did behind the bottom wire which seems a shame, maybe making the wire smaller, or having multiple coming out would still let the viewer see the work you did while not taking away from the whole.
Apart from that i like it, the shading looks nice and the bumpy wood near the tip of the trunk fits well with the wires going up.
Have been watching this.. the curves where bothering me
