You 've done so well with armor rendering I think you should use more hard edges when it comes to face shading especally because the light source is so close. (I recommend lasso +Airbrush combo) In terms of values and colors i think you should choose one key light either moon or campfire and secondary L should be dimmer Other than that try keeping high contrast on the face as first focal point ,deeper shadows etc Hope this helps you out
thank you for your feedback and suggestions Cutterfly,i`ll certainly take your advice onboard, it`s great to know what people think of my art and ways to help me improve.
