As with the first brainy lady in the series, I chose to model Henrietta after her most recognizable photograph. Here's a side-by-side comparison - can you tell which is the original photo?
I'm particularly pleased with how her face turned out. I think the likeness is pretty good - perhaps with a touch less longing & sadness though?
I made her with patterned paper because I love the subtle texture it adds. The background of the ACEO is a couple of graphs I found of her work. The back is covered with a print-out of a photographic plate similar to one Henrietta analyzed in her lifetime.
