Hello, Kim Zanni.
You know, I think you're doing the greatest job on making the prettiest face in the most interesting facial expression and angle. However, I'm still not getting enough of the most forceful expressive and emotional lines of action and rhythm in terms of the head and facial anatomy yet. How would you like to please go for our interactive drawing tutorial here on our site?
The arguement behind this is to do this, gesture drawing is done to not only to draw as quickest as possible, but to capture or record the flexibility and elasticity of the facial expressions and others that you can draw.✍️ It's not to merely make a perfect drawing, but to just be able to record the motion and fluidity of your facial drawings and more. For most details, look into the Vilppu Drawing Manual
here and the Walt Stanchfield books as free PDFs
all here.
Let's hope they've all helped you out.
