Weeping willow

[Biggles]

I am hoping to persuade my young weeping willow to so mature as to ensure one will be able to drive under its graceful, overhung branches before seeing my hundred year olde English country house (that isn't really.) As such I'd much appreciate any and all pointers as to pruning and tie back(s) and cant. The two snapshots reflect coming and going along the drive. Thank you very much.
