Newly Planted Black Gum

Planted a Wildfire Black Gum in New Orleans, LA. over the weekend. 15gallon from a local nursery.

It was severely root bound, so I used the box method and cut about 1.5 inches from each side and an inch off the bottom. Just looking for some advice on how the roots and root-flare look, how the lean in the tree looks, and if I should reduce the co-dominant leader now or wait until the roots establish?

For the lean, most of the day the sun is coming from the direction away from the lean. So I am hoping it will straighten itself out.

And that hole near the roots is from a broken bamboo support. I didn't want to disturb the roots too much more so I left it in.

Any advice is appreciated!
