Assuming you want tips on how to better your ability to shadow yourself:
The first and most important step is acknowledging that there’s always room for improvement. Even the best shadowcasters can find ways to improve their technique. And once you’ve decided that you want to get better at shadowcasting, the next step is finding a teacher or mentor who can help guide you.
If you don’t have access to a teacher, there are still plenty of resources available online and in books. Do some research and find instructional videos or articles that break down the basics of shadowcasting. Once you understand the mechanics of how it works, start practicing on your own.
Start with simple exercises like tracing the outline of your hand with your shadow. As you become more comfortable, try casting shadows of other objects in your environment. And finally, once you’re confident in your abilities, start experimenting with more creative uses of shadows – like using them to create illusions or telling stories through Shadow puppetry.
