The making of Lizard Man, step by step...

i duplicated the image and desaturated it.

i placed the lizard skin on a new layer reduced the opacity played around with it on the liquify tool to mimic the contours of the face and masked it removing the mask to show through where it should be on the face

i found image of an owl cut out the eyes used the free rotate tool to line them up with the eyes in the picture masked them out then painted them back in with the paintbrush
