Hi Richard This could work in a big way but the bright light around nose area is hurting some !!! You did give enough light for the shadow area (fine) might be able to recover some in the RAW conversion ... might be worth trying the double covnersion trick one linear one conventional then putting together !!! .. love that face !!
Agree with Al's comments.
Probably about the best I could do with a jpg. Richard. The muzzle area is completely blown an unrecoverable even with the RAW file most likely.
