Here were some suggestions from a friend Chris Solarski:
"These pencil/drawings drawings I prefer to your marker drawings, without
being able to describe why. They have more 'life' to them, whether that
means anything to you!
I especially like the first and last drawings, in which you've
captured an individual character and, it seems, done something more than
just copy the model.
To push your drawings a little further I'd suggest thinking more
about how you use light and shadow to describe form. You have done this
to some extent. However, in the case of the last drawing, if you'd
visualised the face as a simple cube and decided the light is coming
from the viewers left, this would reinforce the feeling of form by
establishing the side of her face as being in light and the front, in
shadow.
I'd also recommend making more use of construction lines.
Great progress!"
Thanks CAS. I think I need to be in touch with making intelligent
choices with light and shade as a tool rather than as a strict effect of
nature, so that I can in choosing manupulate the form. It is a language
that can tell one story or another with the very same form.
I think that I will try to use construction lines. All good suggestions!
Thanks again!
