Looks good to me. But to steal a line from Roy Scheider's character in Jaws, you're gonna need a bigger boat (er, mount) when this baby reaches adulthood. :-) For now, however, it looks like you did a very nice job.
Well, since it's got Brassavola nodosa as one of its parents, that should help keep it smaller than a standard cattleya hybrid (by "standard cattleya hybrid" I mean anything in the neighborhood of two feet tall by three feet wide). But you could still potentially have something that might end up getting to be fairly large if it's grown well and makes multiple leads (as B. nodosa-bred hybrids often have a tendency to do).
