the perspective of the teapot is strange, it seems a bit 'fisheye' as it rotates around, almost allowing both the spout and the handle to hide behind the body of the pot together
This is a normal effect of perspective projection. If you imagine putting your eye right up close to a teapot in real life, the body of the teapot *will* obscure both the handle and spout, or at least a part of them.
If the effect is too pronounced, you need to reduce the angle of view of your projection, which is equivalent to moving your eye further away from the teapot, for a given size of the projected teapot on the screen.
