I think the trim is pretty nice. 

I added two markups here:

 The toes can definitely come back so that they 'kiss' the white line.  There is a little bit of dead sole that has pushed forward into the small space the toe length has made, making it appear there is no room for more rolling or beveling of the toe.

The sole markup - follow the green line which is actually Cory's white line.  It disappears under a small 'ledge' of sole which is outlined in blue...a false toe callus.  Trim to this line with the toe up on a toe stand, and with the rasp, back the wall.  The red dots show how much wall can come off, both in the toe, and the heel/bar area.

It also appears that the heels are purposefully being left high above the sole.  There is a thought that this encourages sole depth, but only if the horse is in such squishy terrain as to let the heels sink to allow the coffin bone to achieve its more correct orientation with the ground.  Those feet look quite dry so this would not be a trim decision I would make.

The toe- in - the DP x-ray from a few months ago demonstrates a M-L imbalance, as the arrows show from Lavinia's markups.  There also appears to be a deficit or remodeling of the outer aspect of the CB.  The orange lines highlight this.  I also think the x-ray is not quite perpendicular to the CB, so some of this appearance may be more technical than a magnitude of the problem.  

Purple circle shows small development of sidebone, which would be expected with a horse that is loading his foot/weighting to the outside as he breaksover toe-in.

Why he does this, certainly can't say.  Chiro, etc may relieve any discomfort that he has in the upper skeleton from walking a little 'out of kilter' but it is what it is.  There are so many, many toe-in, toe-out horses, (and people with conformational issues!)  and the worst thing anyone can do is try to correct this to appear to be 'normal' on a grown animal.  This is his 'normal'.

IMO, I would trim those heels to be more at the level of live sole plane so the CB can seek the loading pattern it naturally has.  Many feet with such a twist will begin to modify themselves.  I don't see a current photo of the RF sole, but in the photo from several months ago, he clearly is not wearing an odd pattern to his wall.  His foot works for him, and I suspect that it may only show a wear pattern when he gets too long. 

So, lots of words that really boil down to "looks pretty darn good!" and would suggest a few little tweeks.  Not twerks as I first typed in total error!  Darn keyboards!
