Artist Francesco Denicolo has posted up a humongous amount of concept art. This includes everything from Bridlewood, sunnys bedroom, food carts, and more.
One section in particular covers the destruction of Maretime Bay by these creepy black rainbows. Apparently this was an idea that was floated that of course never made it, and they are absolutely freaky looking in concept. I've included more of them beow!
Thanks to Pipp_Petal for the heads up!
