Okay, I appreciate this is not the best, but it's a start. The black rectangle gives a idea of the real ground line (I never take photos straight!). The orange diagonal line shows where the front wall should probably be (it's in line with the newest growth from the coronary band). The black diagonal line is roughly 30 degrees - it also shows the slight bulge in the hair line.
What this picture shows to me is how 'off' the hoof still is. Whilst the trim can (must) be improved, we largely have to wait for this foot to grow while we work hard on the diet, exercise and environment.
