Song Dynasty Chinese painter Ma Yuan's Angler on a Wintry Lake, featuring the oldest known depiction of a fishing reel, 1195 AD. (http://en.wikipedia.org/wiki/File:Angler_on_a_Wintry_Lake,_by_Ma_Yuan,_1195.jpg)
Simple and colorful nature vector illustration of a lake on a sunny day. You can see some clouds in the sky, a log and plants around the lake. The elements of the picture could be rearranged into a minimal landscape or used separately in other illustrations. The shapes and the pretty soft colors create a unique visual style.
