Odd Nerdrum - some odd portraits with a lot of character
Victory Wang - he makes skin out of more colors than I believed possible
Helene Knoop - a few unusual portraits are mixed in with a general Bougoureau (?) genre
Ray Caesar - this 3d artist makes macabre Lolitas on LSD. Disturbing, sometimes funny.
Forum Gallery has a number of interesting portrait artists among other things.
these are mainly commercial portrait painters who pose people, and I find their work too stiff or pretty usually, but I linked these for something of interest.
**Masters of Portrait art - the biggies - Kinstler, Greene, Sanden, Knox, Sherr, Silverman
**Portrait commission group in London - of all these sites, this includes the most experimental portrait artists (mixed in with traditional)
**Stroke of Genius - largest collection of American portrait artists I've found
Andreeva Gallery portrait artists - New Mexico
Russell Fecchion - Tucson artist
**Scott Burdick and Susan Lyon - Very fine realist painters, a generous website with tutorials
Ann Kullberg - colored pencil
Daniel Greene - one of the biggie, New York Subway paintings
Simone Bingemer - a stylized super-realist, pastels and drawing. Her drawing is somewhat like mine, though more prettified I think
Steven Mickle - Pastel only, largely children. Photographic style
Robert Hartshorn Not a style I like, but some interesting lighting
Bart Lindstrom - one of the big names
Linda Vise - somewhat stylized. I don't like her that much, but I like painting white too.
Vincent Chiaramonte - I like the old veteran, the rest are too posed.
Chris Saper - Phoenix artist, writer. Tends to be overheated but facile
Marvin Mattelson - there's something austere about him that I like sometimes.
Ronald Sherr - see the pencil and pastel heads and very realistic portraits with abstract backgrounds
John Ennis - I only like a few.
Sergei Ostroverhy - very stylized super realist
Tony Ryder - Santa Fe classical realist, teacher
John Howard Sanden - author of portrait book, one of the biggies
Jan DolanStylized, good light
Gwenneth Barth - some good pastels
Morgan Weistling - Bougoureau follower to the max, has some demos
Cristina Troufa - unusual, stark portraits
There are very few good ones I've found. Some of the artists above do pencil well.
Pencil Drawing Web Ring - lots of sites, sometimes fun to hunt through, but many bad ones.
