Does your head bob downwards and sway backwards?

Slightly at impact my head is probably half a head's width further backwards and a bit lower than at address (fix). My hips however have gone miles forwards.

For me i think the root cause is dropping the club too far on the inside on the downstroke which means i get 'stuck' so the only way to get 'unstuck' is to lurch forwards with the hips. The move itself is probably correct it's just too much!!
