Honestly, what in this ISN'T completely made of incredible awesome? The line art and ink work is perfectly sleek and clean and beautifully detailed and fragile yet strong, it adds so much interest to their figures and expressions.
And then there's the colouring. The watercolour medium is absolutely perfect. I how it's bordered and paneled and looks like a sheet of leather or skin, with all the gorgeous gradients, water blooms and textures. I love the bright horror of the blood and the instinctual, primitive evokative colouring style.
And the all of the symbolism! It's what keeps me coming back, to look and stare and analyze the art, to sink into the meaning and beauty of it. I'm telling you, this needs to be in an artbook for an amazing video game or anime or something. It's just so breath-taking and compelling!
