Man... I am telling you, this one is a prime candidate to get a trunk chop. See those buds popping off that bulge a couple inches above the soil? Chop just above that, seal it, let it grow a new leader, then whittle your chop site back to make a nice even angle between two new branches, or a 45 degree angle off the back of one... Seal it again... And you will have a tree with a decent start to a thick trunk base, some good movement, and a new leader started that you can make ANYTHING from. As it is, if you try to keep working with it like this... You will always have this odd looking tree that looks like it just barely survived something.
Why not shoot for the "oh that is a cool Bonsai" look, instead of the "yep it is still alive" look?
Aside from that- if you don't want to really go for it- what is your goal with all those branches? 1- the wiring should have a goal of adding some movement to the branches, and I don't see any wiggle there. 2- there are many spots where you have 3-4+ branches coming from the same point in the tree which will create a swelling (like that big knob I keep pointing out and telling you chop to) and reverse taper.
And finally, if it wasn't repotted within the last year or so, you might want to do that before the buds break- go hard on the roots, remove that big lone surface roots, find where there's a good root spread, cut the downward growing roots and any thick roots back HARD, plant it on top of a tile or a board or something to stimulate a nebari!
Not beating you up man, but you seem to have relegated yourself to having a "sad looking tree" when I see a blank canvas with some years of growth under it's belt and some potential if you have to guts to go after it and the vision to carry it out! You will never learn how to develop a tree from scratch if you don't do it a few times- what better material to start with than something you see as a "sad"/ ugly tree anyway?
