These are fantastic! I absolutely adore how you worked your colours for #4, that's the kind of pale I love but never able to achieve! #5 is AMAZING for the text work which (I think) must've been massive.
#7 is a joy to look at, those greens and cyans literally sings (this monitor pushes out cyans in a way I want to cry of joy). And Obviously I LOVE #9 with all my heart, the purple-ish details over the right eyesocket and nose give the icon a very nice depth.
The Category is totally totally you and it's very well put together, it feels like an "escalation", which ends with one of my favourite icons from this batch!
AC#2 is also one I saved in my inspiration folder because it's both light and high-contrast.

I like the alts/rejects too, especially #31 and #32
