All Crescent Moon

This week's Zentangle challenge from the Diva is to use only the tangle Crescent Moon. It's a classic, well-known tangle and one of my "go-to"s. I love these monotangle challenges because they make me think more and not simply do the pattern the same way I always do it. I just wonder why the concept doesn't stick, and I go back to doing it the same way I always do it.  :P

I went to town with this one. Every tile I did gave me more ideas so I did another one. You may be hard pressed to identify Crescent Moon in some cases, but I didn't cheat, it's all Crescent Moon (well, except for a tiny bit of Tipple in the third one).

The little 'petals' in the top middle gave me the idea
for the larger ones at the top right.

I tried a different shaped 'moon' (lower left), and different fills
for the 'moons' (lower right, upper left). I like the tunnel-looking one!

See that interesting bit at the mid-right with the small dots?
It's the result of trying to change something I started and didn't like.
I think this ended up too cluttered.

I did no string here, just three huge 'moons'. I wanted to try the idea of
a fractal tangle, where I started very large and used the same tangle inside
parts of the larger one, then smaller again inside parts of the second one...
Quite interesting! I'd done the white highlights in the 'moons' on the left and right, so I did a
huge highlight in the upper right and filled it with Crescent Moon.

(A fractal tangle...? Hmmm... there's an idea for another monotangle challenge!)
