Taking a shot at making stock art

I’ve started to put together a portfolio of stock illustrations together. It’s quite a balancing act trying to create something that tells a story yet staying open enough that it can be used for lots of different purposes. How do you make something that is generic enough that it can be used for all sorts of stories or topics you’ve never read while not being really boring. This is my favorite one out of the seven I’ve done so far. The stock art/illustration agency I’ve been working with on these have liked what I’ve done so far. Hopefully, I will soon have professional representation.
