Another of my favorite album artists. Man, look at that shading and detail. More to come!

Rio Oka Wardana, professionally known as Digtrash Art, is an Indonesian illustrator and graphic designer based in Batam City, Indonesia. Specializing in dark, surreal, and grotesque visuals, he has become a prominent figure in the underground metal and punk scenes, crafting album covers and merchandise for bands such as Noxis, Inoculation, Cara Neir, and Glacial Tomb. Oka's work is characterized by intricate linework and a fusion of horror and science fiction elements, often reflecting themes of decay and existential dread.

Prompting

Samplers: Euler, DPM++ 2M, DPM SDE, Heun, DDPM

Steps: 25-50 depending on the sampler and how much detail you want

Keywords: None are needed to invoke the style, but these can steer towards certain kinds of images:

teeth, spikes, claws, impaled, skull, skeleton, corpse, pile of corpses, body horror, monster, creature, eldritch abomination, tentacles, vines, roots, worm, parasite, decay, rotting, monochrome, greyscale, fine detail, pointillism, ornate border.

Pointillism will have a significant impact on the image - see the image showcase.

CFG: 5-7. There's a LOT of detail in these images, and most of his work is in greyscale - you need crisp output to avoid stuff smudging and blurring together.

Upscaling

Avoid GAN/ESRGAN models if possible as they can smear/blur fine textures or hallucinate new ones - go for a PSNR oriented model like SwinIR or HAT (I used ChaiNNer 4x RealHAT Sharper for the showcase images.)
