I like Glennmau. It both looks and sounds very nice.
As for your boy, nice expression, he looks quite worried!
I like his ear set, but i'm a little unsure about his head. I can see those Brockhaven lines in his nose and chin. Not bad boning, he's going to run svelte. Thank goodness you won't have the cobbiness problems I'm fighting with Niles! Our smoke is also from Brockhaven lines, and it's easy to keep her trim.
His coat has nice contrast. I'd like to see some pictures of him once he's lost the kitten coat. I'm a little concerned about the side shot you have of him - -some of his spots look like they might be running into stripes near his foreleg. It's not a big deal, just a fault. One breeder I know can't seem to get rid of that left-hand stripe, and she's produced quite a few BW and RW cats.
He looks like a lot of fun, I bet you can't wait to have him home!
