Strong work!
Don't worry about the leaning - that can very easily be fixed by changing the planting angle when you pot up (to a larger pot) or repot (includes bare rooting, root pruning, and a change of soil).
Make sure you consider how tall you want the tree to be, then pinch the tip of the stem when it's at 2/3 of the ht. Example: If you want the tree to max out at 84" tall, pinch the stem when it's 48-56" tall That will give you the remainder of the ht in which to develop the canopy. Do that by allowing every branch to extend until the 3rd leaf is growing, then pinch the branch back to 2 leaves.
That will force new branches to grow in the axils (crotch formed by the branch and leaf stem) as you see above. The new protrusions in the axils of the mature leaves on the <i>Ficus microcarpa</b> cutting are branches. You can maximize branch and leaf density (ramification) by using this method.
