Hi steemies!
For this round the three words that @opheliafu chose are:
tangled - plastic - mermaid
This is my interpretation

I used the pencil, a thin red marker, a thin grey marker and a large marker green water.

I set off from the face of the mermaid ...

Then, looking at her, I thought it might hold something in your hand ...

And that thought came everything else ...

And here is the final ...

I hope you like it!
Thanks
Isa
