Or you could just.. give your suggestions..
OT: looks really nice and we'll balanced. Personally, I'd remove the purples and add more transparents, seeing as though I never use purples or pinks.
it would be... improper to give my suggestions without the esteemed permission of the colorset author....
I'd say axe one of the transparents or one of the blues,
then I'd move the blues under the transparents and then
put the reddish browns under the grayish browns.
And then maybe move the grayscale over to the right a column or two
This just makes it so there's no wasted/empty space which always bothers me in colorsets
