excellent contest! quite challenging and great fun
kinda miss-used a couple of tiles so i might go back and tweak it a bit (same goes for colors ~ i could save a few), but this is more or less my finalized attempt:


40 tiles (suprise, suprise), 31clrs overall, missed the colorramp part of the rules, but i should be fine, ill post 'em when i summon the energy to make 'em
thanks to adam for doing those contests, great to see all the different styles and interpretations it spawns, might dew another one
