The husks in your crush look to be fairly in tack. It looks good to me.
My understanding about shredding the husks too much is that it can cause problems in your mash by not setting up a good filter bed or a stuck mash. And the small pieces can cause more tannin extraction. I've never seen the tannin thing myself but that doesn't mean it doesn't happen. I have had some serious stuck mashes over the years.
