To draw the head at different angles you need to understand the basic form of the head. The Loomis method is a great starting point because it teaches the head as simple shapes. It looks like you’re approaching the head more as a collection of features than as a unified whole. So for example, when you try to tilt the head forward you didn’t account for the overlapping parts of the face. The eyes are almost hidden by the brow line. The nose overlaps the mouth and the ears sit further back. There’s no easy way to learn this unfortunately, it just takes a lot of practice. But if you focus more on basic form and perspective (the ArtWOD beginner road is a great place to start) that will set you up better.
loomis makes sense, though for me the angles clicked more once i started with the jaw. the ball is fine but the jaw is what tilts and turns. maybe try drawing the ear first too, it kinda locks where the skull ends and stops the face sliding around
