He has points on his paws and it looks like ears, and his general coloration as a whole is fairly close to Siamese, so he may have some Siamese ancestry (even more likely if he is especially vocal ). Actually, if you called him a "lynx point Balinese", you might fool a few people...
I agree with Sargon. While there are other colorpointed breeds around, I think that, in your beautiful cat's case, a blue lynx point old-style Balinese would be the best description for a lookalike. Absent a DNA test, we can't be completely sure of the ancestry. I'm definitely leaning more toward Balinese than a Ragdoll or Birman, because his muzzle is more elongated, approaching more of the look of an old-style Balinese.
