using Blender 3D spheres to help with character design

was finding it helpful creating 3D spheres in Blender to block in facial proportions before doing drawovers.  was using scales, translates, rotates in local and world axis of spheres to block in 3D proportions.

used Highlight tool to do a drawover first pass on the screen.

then did another drawover pass using the first pass drawover as a background reference.

for the face 2D sketch was finding it helpful putting the face on its own layer and having hair in a separate layer.  also the 3D reference was on its own layer with opacity 30. 

Happy Sketching!
