From why I see...timing is about as good as it can get. Idle and cruise are about spot on. Can't tell about WOT because I need to see the bottom of the nose where it meets the shell. There should be a carbon ring down there about .100-.125 wide. If it is wider than that it is lean at WOT.
As far as heat range...if it's an NGK plug it's about right. If it's a Champion it's a range, maybe two too hot. If it's an Autolite...I'm guessing...but I'd say PFC to maybe one range warm.
If you want to cut the shell off and post some other pictures I can say more about WOT.
After that, you need a magnifying glass and patience to see if the timing curve is close and stuff like that.
Overall, I'd say your tune up is pretty damn good.
