Selected, copied and pasted the staues on a new layer. Duplicated it, used a curve to pump the colour then a layer mask with radial gradient to highlight one of the faces.
Back to the original layer, duplicated and use colour>threshold then select-by-colour to select the darker part. hid this layer than duplicated the original again and ran a 12px radial blur.
Played with opacity on the various layers.
And flipped horizontally to make it read left to right.
