Ideas for depicting 'talent'

I decided to pick some types of acts that are generally associated with talent shows. Things like singing, playing music, magic, dancing, gymnatics etc. I found some imagery from the web that I could possibly use.

I thought that maybe I could vectorize them and have different examples of talent together on the page. I think vectorizing them would keep the overall style consistant. But the problem is that not all these images are royalty free. And it's quite hard finding the images I want, that are free to use and publish, in this short space of time.
