Werewoke, I am very impressed with your mannequinization. The fact that you captured such dynamic gesturing is really nice to look at. These are great fundamental images for animation-type drawings because they actually capture motion beautifully, however, it does seem that following along a tutorial had some great advantages for the finished look.
I would suggest creating Écorchés to really understand the relations of the muscles in the anatomy. Knowing how the muscles reacts to tilting, pushing, and pulling will help you to maintan the dynamism and motion of your drawings when you practice the mannequinization on your own.
I like the amount of action that these poses bring so I have a suggestion for you if you like to capture dynamic gesturing, Use athletes-in-motion as your references and deconstruct them like so:
Your renderings of the mouth would benefit greatly from studying anatomy, specifically an Écorché of the face. Keep in mind, a sketch and a finished piece are two different things. If you wanted to make a really convincing pencil drawing use a high resolution reference image and spend a few days on it to get that realistic look you're striving for. I personally prefer high contrast references because the dramatic lighting allows me to create more depth and form.
In my study, I've found that creating finished pieces massively improved my sketching techniques. Practice making finished renderings of skulls and references and your sketches will start to look like finished pieces themselves.
Hi there Guelio! First and foremost, I appreciate how you capture the emotions and expressions of the faces in your 30 second/1 min sketches. That helps the viewer relate to the mood of the subject even with very few lines. In your 1min, 5min and 10 min sketches, you do a really. good job at placing the features and maintaining the proportions.
To improve drawing faces in different angles I would practice drawing skulls and contour images in varying angles in order to get a feel for how the proportions and placement shifts as the head turns. You have a pretty good understanding to begin with so it would probably be a good idea to practice with creating midtones, shading, and highlights to create more lighting in your drawings.
