great :) but i feel like the 1. and 2. one the front site should be parallel, specefic the top and under

Looks great! The horizontal lines of the face should be parallel. You have the chin and nose markers going to a different vanishing point than the brows/eyes. On the side plane, you also don't have the jaw going at a steep enough angle (the part that goes from the ear to the chin). Imagine a stunt man driving a motocycle off a ramp. In the original, he goes really high! In yours, he is not getting much air. It would also be good to see an indication for the hair line and mouth

I think you are really on the right track, and I really like how you are defining the form as a geometric shape. Plus I think proportions are looking pretty good. I’d say try to accentuate the “box” nature of the head. Try to draw it as a three dimensional form more than a 2d geometric shape. I did a quick draw over to illustrate (hope you don’t mind). You’ve got this for sure!

This is nice, but I can tell you were drawing with your fingers. Glen draws with his whole arm, that is why he can get those beautiful sweeping lines. Then he comes in and adds detail to the drawing with his fingers.
