Yeah, it's a nicely done one. The only problem it looks like you might have is if the stock grows faster than the graft. That's part of the trouble with mine, is the size jump between the two. I keep hoping to find a solution to this, other than pulling a branch to disguise it.
The biggest tip I can give you is to get the timing of repot correct. If you do it too late, it'll blow off a lot of needles. Luckily, they'll generate a whole new batch in most cases.
