Well... You didn't get it THAT wrong did you!? Looks like you managed to do a pretty spectacular approach and landing!
I think it happens to all of us. Those of us who haven't done it most likely will in the future! It even happens to airliners, and occasionally even the wrong airport altogether!
I've done that and had to go around due to other traffic (admittedly there were 5 runways, the sun was glaring in my eyes and I wasn't aware that my DI had shifted 20 degrees since my last alignment 15minutes before).
Congratulations on the nice landing though! :-)
