YO, THIS GOES HARD
You never fail to amaze me with how you approach coloring your artwork. I'll admit, the background really does scream *eyestrain* more than your previous work tends to, yet it manages to not be super distracting from the main focus of the art itself. In fact, I've noticed as I'm writing that there's some hidden text inside the background itself. No clue what any of it means, but the FNAF kid in me has a soft spot for finding little "easter eggs" like that in images.
The crimson coat is also very visually pleasing to me. It almost looks like someone tried visualizing rushing blood with the way the light and darker shades of red spread out across the coat. And the blue on the zipper, shirt and eyes provides a nice contrast!
And having noticed that this art is in relation to Death Note, the signature text having an edgy font that kinda resembles DN's logo is some great attention to detail as well!
