Help with Guideline 2.5.10 - Performance - Software Requirements

I created an app for fine art for iOS and for the screenshots, I originally had art by actual artist so it was denied by Apple: under the guideline 2.5.10 – performance – software requirements. "To resolve this issue, please revise your app to complete remove or fully configure any partially implemented features. Please ensure your screenshots do not include any images of demo, test, or any incomplete content. To resolve this issue, please revise your app to complete, remove, or fully configure any partially implemented features. Please ensure your screenshots do not include any images of demo, test, or other incomplete content."

This is what Apple reviewer said, so I removed the screenshots of the actual artwork and replace them with the app's logo and I am still getting denied. I don’t know what to do, complete removal of any images would hinder showing off the app features. I asked them to clarify and they repeated the statement above.
