If the goal is to make it look more painterly, then you need to allow the brushwork to be more obvious. What you have now looks interesting, but it has a distinct collage of textures look, and all the sharp edges looks very digital instead of organic.
What you should try, is to allow your brushstrokes to remain visible instead of making everything so clean. Allow the bristle marks and brush textures to remain. Don’t blend and smooth everything so much that all sense of spontaneity and expressiveness are gone.
Look at master painters like John Singer Sargent, Anders Zorn, Richard Schmid, Pino Daeni, Craig Mullins, Jaime Jones, Zhaoming Wu, Daniel Gerhartz, Susan Lyon, etc., and do some master copies of their paintings to learn how they approach their brushwork. Analyze how the direction, thickness, and sharpness of the brushstrokes coincide with the turning of the forms and shifting of values. Look at how they use brushwork to create the illusion of textures and surface properties. Study how they simplify forms and use selective detailing to make focal points more interesting and supporting areas less competitive with the focal points.
