Edit the first photo: add a new tattoo on the upper arm / bicep of the arm that has the black forearm tattoo, based on the moon and sakura branch design in the second image. Keep the existing chest watercolor tree tattoo and forearm black oni mask tattoo exactly as they are. The new tattoo should wrap naturally around the bicep, follow the skin curvature and lighting, look healed and realistic, and visually connect the chest tattoo and forearm tattoo. Keep everything else in the photo unchanged.
