Good for you(& your horse) that you're striving to get yourself educated rather than just trusting to whatever 'expert' is at hand!
Yes, there is a fair bit of separation, but only seeing a foot from those angles, don't know whether it's reasonably superficial & just related to the excessive hoof wall, or otherwise. Check out the links in my signature & one has some good tips for photo taking for critique.
While assuming the farriery was good & the horse's feet were in decent shape, 9 months of shoeing shouldn't really affect too much IMO, immature feet being shod will potentially do more damage & prevent further development. It does depend on the environment too, as to how much the peripheral loading effects function & therefore form. For eg. if he's predominantly on hard footing, the extra height the sole's off the ground, with either a shoe or currently, the long hoof walls, this will put more leverage on the laminae and can also allow the unsupported sole to become lower/thinner.
The biggest thing I see with these pics is that it appears the horse has very thin soles. This is evidenced mainly by the lack of depth of the collateral groove at the apex of the frog and the ridge of sole around it that continues from the bars. If you're working your horse on hard/rough footing, he doesn't need iodine to just make his soles a bit harder, they need to *grow thicker* to provide enough protection. If not, he's at risk of stone bruise abscessing. Therefore I'd be providing protection for him in the form of hoof boots or such, until his soles can grow healthy & thick.
