Is that your rug and furniture? Use a color from the rug for the walls. Paint all walls same. Accent walls are out.

This is now. Pic doesn’t do it justice

Nothing really rustic about anything you selected

The white fireplace surround looks good, but the wall color, tile surround color, ceiling color and floor color are somewhat out of sync with each other.
If the gray-tone flooring has to stay, the rest can change as needed.....but I am hoping that gray flooring is on its way out. Wood-toned flooring (in most brown tones) will go with anything.
