If he wanted to draw a hand with an inverted arm (assuming it was a hand with an inverted arm), he needed to first understand the structure and dynamic principles of the arm. Judging from the ratio of the arm structure, the length of the upper arm and the lower arm was about 1:1, and the length of the hand was about 60% to 80% of the lower arm. When the arm was vertically down, the elbow joint was basically parallel to the waist, and the wrist was about to reach the hip. The arm was made up of the humerus of the upper arm, the radius and ulna of the forearm. When the arm rotated, the bones of the forearm would rotate accordingly. This was the basis for the forward and backward rotation of the arm. In terms of muscles, the deltoid muscle was more prominent on the upper arm, which was connected to the chest muscle on the inner side. The biceps was on the inner side of the arm, and the triceps was on the outer side. The forearm was connected to the root of the thumb by the brachioradial muscle from the gap between the biceps and triceps. When the arm was in the reverse position, these muscles would produce different stretching and contracting states due to the twisting of the arm. For the dynamic rendering of the arm, the bending of the arm would cause the muscles to contract and stretch, and the outer outline would also change accordingly. First, he determined the positions of the three key parts, the shoulder, elbow, and wrist, in the reverse arm posture. The ratio of the shoulder to the elbow and the elbow to the wrist was about 1:1. After determining the general dynamic posture of the arm, he began to draw the hand. If it was the drawing of an anime character's arm, one could first summarize the arm muscles with a geometric shape. For example, the arm could be simplified into a cylinder to determine the dynamic and proportional relationship of the arm, and then add muscle structure according to the twisting of the arm. The male arm muscles could be drawn more clearly, and the female arm was relatively slender but also had a small amount of muscles. Pay attention to the smoothness of the lines during the drawing process, and also pay attention to the relationship between the arms, chest, and shoulders. For example, when the arms are twisted in the opposite direction, the muscles in the chest and shoulders may have a pulling feeling and other details. Read more exciting novels for free
