Hey there! Overall, you already have a really solid foundation! The main issue with the side-profile pose is actually the legs more than the arm. As for the arm, you could simply define the muscles a bit better (I don’t remember the muscle names haha, but you’ll see what I mean in the example) and draw the hand in a more neutral position instead of spreading the fingers apart. Now, regarding the legs: Legs aren’t completely straight. Naturally, they tend to form a long “S” shape, which becomes much more noticeable in side views. If you stand up straight, you’ll notice that the knee doesn’t align perfectly vertically; it tends to push slightly backward. That’s why the leg silhouette creates that elongated “S” rhythm. Also, this character doesn’t really have normal human legs. They feel more like a hybrid between animal and human anatomy. Because of that, the section from the ankle to the heel shouldn’t behave like a regular human leg. Instead, there should be an additional extension, more similar to a mammal’s hind leg, followed by the foot itself. Hope this helps!
