Due to the slightly higher poly count of my mesh, there are increased vertices and finer details. Weight painting on such a high-poly mesh demands more complexity and time, necessitating meticulous attention to detail to achieve smooth deformations. Considering the final pose of my character, additional time is required to address the deformations around the neck area.
Continue working on painting the skin weights. For the legs, a more efficient approach to ensure that the skin weights of each leg don't affect each other is by using the component edit and setting the weight of the other leg to 0. This method speeds up the process.
