Some of the coronet bands look like roller coasters.
"hey I like roller coasters" They should be nice and even all the way around the hoof. The one that you can see this most clearly on is the inside of the right front. See how high it is pushed up......then look at the bottom of the RF where the hoof wall meets the sole.....notice all those cracks. There's too much hoof wall touching the ground and it's causing excess pressure which is pushing the coronet bands up in those areas.
The hoof wall will benefit more from having a bevel created from the bottom of the hoof and not just the top. When you round from the top only it looks nice but it's not providing any relief to the bottom of the wall where it's needed most...and when it's left flat like that it creates pressure and it causes tearing and eventually if left too long the seperation will eventually create lamellar wedges.
If you consider the hoof wall growing down at an angle, you want to create a bevel from the bottom, on the hoof wall which will be flat "perpendicular" to the angle which the wall grows down.....not to the angle of the sole. Actually lemme find a video which explains it much better......
It looks like you are doing well....learn elpo hoof mapping and watch Linda's videos, "that's one of her videos I linked to", and take your trimming to the next level. If you watch "hoof trimming to the true anatomy of the equine foot part 1" and work your way forward through her videos you will get a pretty good grasp of hoof mapping.
