In the early 2000s I was involved in a fan project based on the Joss Whedon series "Buffy the Vampire Slayer" as a designer and art director. The goal was to create truly realistic icons from the series while maintaining their functionality. That is, the readability of the characters they reflect in the system, the shape, sharpness, and contrast of the elements on a small icon on the desktop. Such ambitions led to the fact that most of the icons were drawn by hand, and some had a phenomenal amount of detail (since CoverFlow on the Mac allowed you to show a large icon in the window).
The problem was that the show itself was filmed in the late nineties, and it must be said to be far from shining with high resolution pictures. When you watch a movie, it's okay, our brain adapts the flaws, plus you still follow the plot, not just the quality of the picture. But transferring some of the objects and even the characters from the screen was just impossible. They were just blurry screenshots of low quality and dubious detail. So I began to draw and actually recreate the world of the series by eye, in order to transfer it to the high resolution of modern computers.
One of the toughest ones was Spike, one of the key characters in the series. Who had to be not just recreated, but practically risked from scratch, using tablet drawing techniques, textures, effects and shadows available in a visual editor. This is one of the pieces where Photoshop was used 100% along with my drawing skills, but first things first.
The only sane thing I could find on the internet was this picture:
