Decided to draw different light from references. Reading Anatomy for Fantasy Artists and trying to implement some ideas.
Tools: Photoshop + Wacom tablet.
|First layer with 2 tones. 1 for shadow and 1 for light.|
|One more tone for shadow|
|One more layer with deep darck tone. This is final b/w version.|
|Add overlay layer with base colors.|
|Added second light and background + small touches on face.|
