One change to consider if it is comfortable/secure for you to do is to grip as low as you can with your hands. i.e. get them lower. What I have found is the higher you have your hands the higher your head will be as you have to sight over them. If you can manage to get them lower you will find a natural tendency to drop your head more. Sorry to nitpick as that posture is light years ahead of what you had, but we are the marginal crowd, right?
