Those two picture are great. The first one have a wide range from black to white, a lot of textures and details to keep the eyes from getting away. The second one, is like 24 frames to read, here again lot of textures and lighting effect. Nice work.. Bravo ! Sorry for my poor english, i would have like to say more, but my vocabulary is too much limited to do that. Hope you can make sense of what i am trying to say :D Best wishes for your exposition :)
