Hi Eny, congratulations on finishing this lesson, I'll try to critique your work as best as I can.
-The first thing I notice is that throughout the lesson you are leaving a lot of empty space, this is very limiting and I think has affected each part of your constructions, space and time are the two big factors that come with the constructional drawing lessons so use both of them to the best of your ability.
I'll try to address each step of your constructions separately.
Head Construction
You should stick strictly to the demo shown here, down to the smallest detail, the eye socket are better off as a pentagon with the point facing downwards. This provides a wedge for the muzzle to fit into, and a flat edge across the top for the forehead/brow ridge to rest upon. You are moving in the right direction here though you are not thinking about it enough, as in most cases it will come together very loosely, all of it comes down to the fact that we are drawing in 3D, and this applies to the eyeballs too, one way to reinforce them is to draw the eyelids as shown here.
Proportions
Proportions is not a big point of focus when it comes to the principles studied in Drawabox, but I wanted to stress one thing, and that is that you tend to make the ribcage smaller than it should be, as pointed out in the lesson the ribcage should occupy roughy 1/2 and the pelvis 1/4, you can check your drawings and see that you drew the ribcage smaller than it needed to be in most cases. You can clearly see it in this drawing, and this one.
Leg Construction
I think this is the weakest point in your drawings, and one where you will need to keep working on, you should always stick strictly to the sausage method as was taught in Lesson 4, right now what you are doing is trying to draw the legs precisely as they are and translate it to the page.
What you should aim for instead, is to start from simple to complex, you can see it in practice in these demos, the ant leg demo, and the dog leg demo.
If we take a look at this panda bear legs you only modified the silhouette with a line, to match what you saw in your reference, these bears are also a good expample where you only added a flat shape without any consideration.
Additional Masses
As opposed to the legs, this is an area where your work is coming long nicely, but as I mentioned at the beginning of this critique, the fact that you limited the space you were working with affected it, so in this case I'll leave you with some notes that should help you improve.
Next Steps:
To see how well you absorbed this information I'll ask you to do 3-5 more constructions. Take as much time as you need to, and when done reply to me with your revisions and I'll gladly review them.
