Great work on the intersection of the 2 cylinders which is not obvious. I would have tried to continue slightly the line instead of having a sharp stop on the vertical line; kind of ghosting the continuation like for all other ellipses

Same here regarding tanks

Pretty cool. When I looked at your attempt at model 2 my impression was that the face was too flat, that the eyes where on the same plane as the nose, instead of being in a recess as they should be. I noticed that you have correctly indicated the plane bellow the brow ridge and the plane of the cheek bone but somehow didn’t manage to put the eye in the right place. I believe this is because you didn’t capture properly the planes needed to show the nose on top of those 2 planes and ended up putting the right eye too far on the right. Final comment the mouth is a cylinder or in the context of this exercices a box on top of the face plane. Rather than long text, I have tried to Illustrate my point with a sketch on top of yours automatically when you construct things that way, you will avoid the mistake mentioned in the other comment of having the left eye too big

Dear Vin, i think you are on the right track with your drawings and really need to focus on identifying where are the cube’s faces on the model. I see nothing really wrong on your attempt at model 1, you can just continue trying to add step by step extra volumes. This is where digital is really helpful because it is easier to keep things clean. I have tried quick on top of your drawing to show what I mean. i am less convinced by your tracing because although they look cool because they show very nice line quality shapes on top of the picture, they actually lack accuracy regarding where the plane changes are. I have tried again in red to add on top of one of your tracings where I see the plane changes. i hope this helps a bit

I find your portraits pretty successful but my understanding was that the goal was not ti put a box around a portrait but rather to stylize a portrait with linear volumes that show the perspective of the head volume. key lines contour lines like brow line and eye to too if ear are not visible on your drawings.

Looks good indeed. I have 2 comments though: 1. pencil and paper is fantastic but your work would benefit from more attention on how it is digitized. Not everybody can afford a scanner which helps a lot but there are ways of taking photos and reworking them that help the viewer get a proper feel for what you really did. I even believe there were videos from Stan explaining that long time ago. 2. regarding model 5. You did a great job capturing the extreme perspective. I think the lower part of the face can be represented with 2 volumes on top of each other instead of one as you did. The first one corresponds to the upper jaw; the second one to the rest of the bottom

Looks great! Very week thought through construction. I believe on 15 you could suggest better the intersection of the bottom of the chin with the neck with an S curve instead of a C as you currently have. At least on the left side, the curvature of the intersection should be same as that of the chin

Very nice pen and ink piece

Nice job but be careful checking the alignment of eyes, bottom of nose and mouth.

too rarely seen from my point of view: a digital painting that looks like traditional art and doesn’t fall in some kind of caricatural over polished and uniformity trap

I specially like the scary look of the beard guy. Very nicely done On the lady, I find the tonal transitions on the face too brutal which makes the final piece look a bit unfinished
