Avoid creating fingers with unnatural length or excessive curvature, proportional discrepancies between the length of the fingers and the width of the palm, as well as anatomical inaccuracies, such as incorrect bends or joint positions. Do not use rough skin textures that can give the hand an unnatural appearance, and avoid creating fingers that seem too stiff or immobile, depriving the image of expressiveness. The fingers should not merge with each other or have indistinct contours, each finger should be clearly visible and differentiated. Eliminate any signs of asymmetry that may disrupt the visual balance of the hand, and avoid exaggerating with abstract shapes or stylization that detracts from a realistic image.
