I agree with much of what Missy says, I think, but find some of it hard to understand too(Eg. Why have you changed the angle of vertical line in first 2 pics? What do you mean by heel 'going up & up'? It appears from your drawings that you want to lower the toe into the sole plane?).
So anyway, my opinion on these pics.... To begin, looks like you've made fair improvements.
Basically appears that the ground surface at the toe is short enough(sole level), but the heels could probably be lowered a tad more & the quarters appear quite a bit longer, hence the separation - Agree with Missy about the wall height being balanced according to the sole plane, so it should all be about sole level. I'd probably(it depends) keep it sole level or near until the hooves were in better shape. I'd also lower the bars a tad, so they are also at/near sole level.
I would bevel the toes from a tad further back than it appears, into the white line and do it right around from 10 to 2(imagining the ground surface as a clock face with 12 @ point of frog) rather than just the tip(between 11 & 1). I would also bevel/roll the flared quarters strongly, to or near the whiteline after balancing them on the ground surface, to relieve any leverage until they grow down well attached. When toes & quarters no longer show any stretching in the white line, then I'd begin the bevel somewhere around mid wall.
It does appear there *could* be a *slight* imbalance in heel heights, but I wouldn't want to conclude anything in detail, because I'm aware that pictures are often unclear & can be very misleading, depending on how they're taken & the angle they're on. Eg. I could show you a fresh trimmed foot sighting down the heel, from a different angles, which make it appear one heel's higher in one pic but the opposite higher in the next pic.
Forget if you gave details in the other thread, but do you ride this horse in boots or bare? I'd be inclined to use frog support pads, depending on terrain, as his frogs(& digital cushions) look a little weak & heels are high in comparison. Given the weak frogs, it may be best to leave a tad extra heel height for now & use the pads to provide more comfortable stimulation to get them becoming stronger. Frog support also tends to help underrun heels relax.
