modelman,
I think you have done fantastic after such an eventful (like anyone else has ever made a mistake , lol, ask me! ) and challenging day, to pull off a decent landing , despite the workload of an EFATO and chockka block ATC (which is often normal).
Stick with it mate, you appear to be made for it, everyone doubts themselves after such days, and its only ourselves which we can measure against.
You have already said you enjoy it enormously, thats enough for me to say what I've said. keep at it!
cheers
