Such an amazing set ! I know nothing about this show and never even heard of it , so I was greatly interested to read about the description as well. Might give this one a try also since obviously you're really passionate about the show.
Overall , this set has a very neutral pastel and grungy vibe going on , with lots of heavy layering , text work and some intricate blocking. MY immediate favorite is 14 , the neatness of the bg coupled with how distinctly the subjects stand out because of the contrasting colors n clarity , n the bold tiny size - beautiful. Also , loved the 4 color blocking with bw subjects in 15. 3 is another great icon, crop , the pastel beige color n blue eyes , the smattering of grunge sparkles - perfect.
Great blocking composition is 10 and 16 , especially the way you've used text as borders , that's interesting. I also love the compositions of 5, 6, 9 and 18. The way you've used texts to fill up space in 7 n the mix and match of fonts look amazing. 13 is another lovely monotone icon and the composition is striking. Looking forward to your icons every month as an inspiration .
