This tangle evolved from a single orb. I found that the bigger the orb, the easier it is to add the curved lines. I put the axes in before I add the curved lines so I am aware that they are going in different directions.
Where the orbs come together you can fill them in with smaller orbs, by coloring it black, or whatever works for you. I like to shade where the curved lines meet at the top and bottom of the orb.
Enjoy the tangle!
