The realness shines through. At no point was anything taken through an A-D process, or an A-D-A process. No plug ins were used. No computer-aided tracing, drawing, smoothing, post-processing. No leaning on powerful fix-it-in-post tricks.
It all had to be better at the source. And even if it wasn't brilliant, at least it was real.
Maybe this is a case of work vs lazy or real vs fake.
