I've recently got into that "hipster" trend of long shadowing. I have seen this example quite a lot, and have tried replicating it myself. No efforts have been successful though. And even the close ones seemed like to much work for that effect.
Main issue i'm having are the middle green triangles, and their shadows down. If you notice they fold over the background circle, which is another issue of mine.
How can I replicate this technique as accurately as the image?
