Diva's Challenge #286: Straight to It; and belated Diva's Challenge #285: Relax, bro

This week the Diva's challenge is to ONLY use straight lines.  

Either use all straight line tangles, or try using a curvy 

lined tangle, but with straight lines - for example, 

what would crescent moon look like if it was all straight?

I decided to take a tile I had done previously with all 

curved line tangles, and convert it to straight lines. 

This was the original tile:

I did this one first:

but wasn't totally satisfied with it; don't know why.

So  then I did this one:

After I finished it, I realized that I had inadvertently changed 

the direction of some of the line work. Can you find it?

I never posted my Diva challenge for last week.

The challenge was to just relax and tangle; 

tangle as if we weren’t showing it to anyone. 

I started out by penciling a string randomly,

without looking. Then I filled the sections with 

some of my go-to tangles, whatever seemed to fit 

the space. The leftover sections that were too small

for full tangles I just auraed. Then some shading, 

and, Voila!
