It can be a tree again.👍👍😀
First. I'd get rid of all that bottom growth.
Then :
Cut all the dead branches off, SHORT ! About 1/2 inch to green. The less dead wood, the better.
Then work on green branches.
At each cluster of new growth. Trim, all but 3-5 branches off, going in direction you desire the tree to look.
Your sculpting the main scaffolding of tree, by forcing it to grow the way you want it. So keep any undesirable side branches, or undesirable buds cut or broke off. Little buds can be snapped off by hand.
When your small clusters of 3-5 branches get to be 8-10 inches, you can decide, which one or ones you want leave.
When branches reach the desired length you want them to branch off at, simply pinch the tip off.
You get the basic idea.
Carry on buddy. 👍👍
