in my experience, your submission does not have to be a carbon copy of what you end up making. you can check the boxes to make them trust your artistic ability - then you can make it yours, within reason. the money controls the art outcome, until you're banksy. a lot of great artists are able to stylistically and thematically change their art on a whim, by studying the materials/style and putting conscious effort in. this is not rare. modern art does not require mastery by any means and some of the more successful artists actively avoid perfectionism.
Modern art may not require visible utter technical mastery, even though sometimes it's demonstrated, too. What I mean by mastery is the ability to produce such an oevre that checks all the right boxes, and does not check any wrong boxes. In this regard, being edgy and provocative is the right trait to demonstrate, while overstepping it and, say, showing something that can be seen as bigotry is not comme il faut. Navigating these boundaries efficiently is what I also mean by mastery.
