Its great to take into account how the tree looks from all angles including above. but its your chosen front which is the most important, get that right and the rest more often than not, will fall into place. that means getting some depth and order into the branches. im not a ficus fan, nor do i know much about them, but i think something like this would be a good starting point
no crossing bits, movement in the branches, balance....thats the type of thing i would be looking at. and judging by your styling i think you would like this type of thing.
you could possibly do further branch selection here n there as well, i dont think you need as many bar branches as you have. just take your time. you also dont want the gaps too big between your branches. note the tree above
ps not my tree btw, a google image
