I feel like I remember a popular artist who draws exclusively with "solid" borders, as opposed to gradient lines. I'm sure it wasn't a one-off, low-effort sketch, this is his main theme. And not just small pics, like pic related or tomu.
This has been bugging me for days, since I can't find any in my artist folders on my HDD that fit what I remember.
Does anyone know who I'm talking about, or even what the hell I'm on about?
