If it wasn't lock to lock, then it wasn't a tank slapper!

By the sounds of it there wasn't a lot else you could've done. It's all very well people saying 'slow down' but would that have really made much difference? I'd rather choose good technique over slowing down to cover up loads of mistakes.
Your biggest enemy is being surprised. Your natural instincts take over and it's them that'll get you killed.
Once you're committed to the corner that's pretty much it. If you can't see around it, stay away from the white line.
Only you know if you approached the corner badly and you can't avoid every muppet on the road hell bent on killing you.
From the sounds of it you did ok so don't beat yourself up. Keep it smooth and controlled, gather as much info about the road ahead as possible and you won't go far wrong.
