Loomis heads use 2 cuts/shaves to the sphere. These will look elipse if the face is not in profile. The shape of this elipse, centre, major and minor axis has a lot to do with the perspective if a circle on a box rotating in the space. Imagine the choped off sphere as a very round tyre of a vehicle, determine the perpendicular minor axis of the chopped elipse. Imagine the elipse on a square plane, the diagonals intersecting point will be the real centre of the circle, which will be little away from the centre of the elipse.This all will help you determine the orientation of the chopped of sphere, placement of various facial features.

Hey Christopher, One of the best exercises i can recommend to people is to practice drawing cubes and spheres with the same perspective. Once one learns to do this accurately, drawing the loomis head with the same perspective(x axis rotation, y axis rotation and z axis rotation as well as size) is much easier. I’ve attached an image describing the exercise. The centre of the cubes faces should be tangent to the sphere. Hope this helps

I looked at some of your drawings. I would say you lack some of the fundamental drawing knowledge/skills. I looked at your Instagram and there were a lot of Pokemon drawings, they had a lot of proportional mistakes and you seem to also lack perspective skills . I would highly suggest you work on those first. The use of the box is to break things down into their basic structure. the image below is by one of the instructors marshal vandruff, and he is breaking down the concept of dinosaur into many different forms to simplify the drawing. I would suggest you study from these resources : For basic proportion: Drawing on the right side of the Brain by Betty Edwards &/or Keys to Drawing by Bert Dodson For perspective - Scott Robertson has a really good book called how to draw (this is what I studied from ) there are courses by marshal vandruff and I think there is also a book by peter han.

Christopher, I noticed no one had replied to this so I'll add my two cents. Loomis heads are a construction based approach of drawing the portrait. Using the fundamental perspective of a box you can add/remove sections to that box and begin to build a more complicated form like the head. If you are having trouble drawing a portrait, it's always good to start with a simpler form and work with that. I hope that gives some insight into what Stan mentioned, let me know if you have any more questions.
