Monthly Challenge - Celtic - Number 4

I was up until 4:30 starting #4 when my Ipad and Apple pencil ran out of battery power.  Just one of those nights where I was tired but not sleepy.  Even after I was forced to stop, I struggled falling asleep.

 After I slept a few hours, I proceeded to complete the fourth design.

These are definitely becoming easier to do where I'm actually enjoying working through to see what I can come up with.

Not sure if I'll do any more at this point but at least I won't dread doing so if I choose to continue.
