Looking for comments on these hooves please…

I strongly suspect that you have negative coffin bone angles there because of the curved profile of the front of the foot and the low heel. Does the horse have any issues with the back or with PSD?
This is what I see, a broken forward hoof pastern axis, especially the first one. If the horse has behavioural problems or difficulty in canter I'd be especially worried.
 
The hoof looks better in this one, heels not running forward, but the hoof pastern axis still looks broken forward - as far as you can tell from this picture (not much of the leg and horse standing on a soft surface).
 
I would agree with the possibility of suspensory problems. My friend’s horse has back hooves like these and they’re progressively getting more rounded in front due to having psd.
 
What do the soles look like? Has your new farrier rasped right down to sole level all round?
The look of the soles hasn’t changed that dramatically from what I can remember from the “before” stage.

From what I can tell from the limited view shown in the two more recent pics he is standing with his hinds quite camped under.

Is that normal for him?
Think possibly a bad photo angle… not normally camped under
