Thank you all for the advice and I think I will follow all the advice posted above.
I already pruned a ton of foliage off the top, but I'll keep the top managed to make sure it doesn't steal too much energy from the cascade branch. I didn't realize how straight and parallel to the ground the cascase was until I took these pictures. I have some tough copper wire from Lowe's that I'll put on there and see if I can add some movement. I left as much as possible on the jins at first, since you can always remove more later, but I do agree they are too long and skinny right now and need to be filed down.
I liked how this one turned out so I went and bought another one, I'll post pictures of that one along with before pictures once I get it done. It's not a nana like this one so the foliage isn't as dense but it does have a nice thick trunk.
