When is the ruling on drawing cartoon characters with features that do not match those of real human beings permissible, and is it permissible to draw half of the body or the head and neck of such characters?

Drawing animate beings is prohibited, and this includes drawing imaginary animate beings that have no real-world counterpart. However, drawing only part of the image, such as the head, or the head with the neck, or the entire body without the head, is permissible. This is because removing a part of the image essential for life (without which life cannot exist) removes it from the ruling of prohibited drawing.
