Thanks for the feature Julia, and some other great selections here as well! I will share a little exclusive tidbit here for your readers, I used two style images to create the colors in the piece you featured above (applying the style images to a black and white base image I created using the two woodcut style images I shared in the original post). Here are the color style images if anyone wants to play around with recreating a similar color palette in Deep Dream (combine the outputs from each style image on different layers in PhotoShop, over the original base image, setting the blend mode to "multiply" for the two output style images, then play around with transparency of each layer to achieve desired effect):
Primary color driver is a crop of beautiful opal from Yowah, Australia:

Secondary color driver is a crop of coral reef from Pixabay (this also is one of the primary form/texture drivers in the image, along with the original photograph of kelp which is coming through very faintly):
