The Diva has challenged us to create a small 2×2 tile, Bijou style. Love the interview she has posted with Bijou. Sounds like he loves America. I love these little tiles, so quick to do up and still give you the whole zentangle experience.
I used official tangles:
B BB I Isochar J Jonqal O Opus U Umble
CZT, Katy Harris Abbott has a CZT tile exchange going on and she presented the idea of the tangles starting with the letters of Bijou.

Creative idea for which tangles to use -always my worst problem. Lovely tile.
What a great idea and wonderful solution! Your shading is amazing.
