Man Pictures
Michelle and Her Man pictures - / her man would look alot better than that / I would lower the color intensity and the contrast on her face to match the source painting
Snowman Pool pictures - Source
Lizardman pictures - DNA Tests Exonerate 'Lizard Man' In Van Attack sources 
Huckabee Woman pictures - / Wonderful idea, however, the face could use a bit more contrast. It looks a little washed out/faded.
Man on Pizza pictures - / I would stretch the pizza to fit the entire pic and darken or delete the pizza background. But great idea.
Gwen Stefani + Marilyn Manson pictures - / Just when you thought MM couldn't get creepier
Superman Returns pictures - As always...full view looks a tad better. / shadow on left side needs lightening a bit. Otherwise good entry.
The Mandarin Man pictures - 
Gary Oldman as Rembrandt pictures - / Has a look of Charles Bronson about it. Nicely done though. / I think if you worked on the nose it would be better / Impressive, though it is a bit hard to recognize Gary. / Skilful blending of the eyes and mouth, but the source-pic hooter spoils the resemblance
