I think weave 'em lol
it's now or nevermore
Yes the cracked stalk, careful there indeed -- can you somehow tie/ducttape it to another part, like a strong side branch, so it gets fixed in position and doesn't break through when you manipulate the branches?
Yeah I see those branches that are taller right on the screen edge -- but you can weave em towards those spots of the screen that are still empty.
Pull them under the screen.
Bend the branches a few times in the direction they're supposed to go, first very lightly as not to break anything, especially if they're already getting a tad "woody". Make use of the bend they already have from straining towards the light from under the screen if you can. You can also tie the branch to the screen where you're going to make them change direction.
Branches can be detoured up to 180° from where they were going
