You absolutely can if that is what you want to do. We 100% support you as an artist. Just because you have Style Match (TM) to manage your style and brand identity, it doesn't mean you can't go into your favorite images and go wild on them.
You as an artist are the only one who will know when and what images are right to break the mold of consistency.
What we DO NOT recommend doing is trying to restyle your images. If your brand / style has changed please contact your dedicated Professional Style Consultant to update your Style Match (TM) to reflect your brand.
