This is a pitch that i did, for a mini-series featuring Shang Chi and the MI13, at Marvel, some time ago. The pitch was picked but nothing was ever done with it.
The general pitch was around Shang and his classic pals from the 70s, with a 70s vibe to it, lots of fun action and acrobatics, and the visual approach from "man of Uncle" - but in a modern setting. Everything was painted in traditional watercolors and acrylics.
Actually, if you're interested, some of these originals are still available to be purchased.
