I'm still not sure what to do.
Does this look kinda like a tree?
You may want to spin it around and see how it looks for other 'sides'. It will be more believable if branches in the back (from your vantage point) are thinner and ones in front are thicker. For instance, if the branch in the middle of the pic above is thicker than the other two, the view 180 degrees (opposite) this would be better. Another aspect is that one wants the tree to not be recoiling in horror which is how it feels when the trunk and branches run away. It is much friendlier when it tilts or bows toward the viewer (front). Finally, the nebari is maybe the most important single aspect of a good bonsai. Choose the view with the best of these to be 'the front'.
Now, about those primary branches. Even in the cropped view I've given you they seem quite taperless and somewhat unnatural. Remedies are to chase the foliage down until you can chop what is presently there and replace it with new branches that you spend a few years chopping and growing to develop taper and movement - years. Placing foliage to cross in front will sometimes trick 'the eye' into not noticing this (straight and taperless) and is something that could be done in the next season or two.
The point is, what I've shown you (above) is your tree. You need to decide how to fill out the top to make an attractive bonsai (and attractive to you is all that matters). What you decide you want will dictate your next steps.
Wrestle with it!
