based on the style and characteristics of the five skill icons provided above, create a new skill icon. the image should feature a silhouette of a person seen from behind, with their hands placed on their waist and their latissimus dorsi muscles flared out wide. the pose should emphasize a v-taper physique and detailed musculature, ensuring anatomically correct muscle structure. use the pose from the fifth reference image, but adjust the camera angle to a low-angle (looking up) perspective—this is crucial for creating an imposing, centered, and high-impact visual.
