Another play to try & get shadows in right place. Bit of nightmare having the rim of helmet . Did try to bounce some back with white paper as reflector, but it eother lost all the shadows, or at least most on face apart form the darkest one caused by helmet. Note I wanted to keep it dark & moody, so have no problems with shadows blending into background on this shot.
Ah well, will play some more & sort out lighting for grad background
