IAEA patch is a nice touch! To lean into the nuclear theme I'd recommended a respirator around her neck, those disposable plastic boot covers, and a dosimeter flapping on a lanyard
Very nice, I'd read that comic book. Don't forget to also pay attention in class.
Any insight you can share on how you pick the colors light to shade matches?
The choices were honestly just looking at what colors made sense given the limits of a 5 color highlighter set. Yellow and red logically go together. Yellow and green logically go together. Purple doesn't fit a proper color theory scheme, but it was the darkest available color.
The purple shade with the yellow /green highlight is surprisingly working very well. I thought it might be from some obscure color wheel things. Lots of very cool details in there. The muzzle flash lighting is very well done. I'm taking notes.
