Portraits of people can be airbrushed, but also painted in oil paint or acrylics. Just like the pet portraits I charge per square inch, providing an opportunity to get a painting of your loved one(s) at all price levels.
A portrait in grey scale (with black background) is another cheaper option. Airbrushed portraits can be done on canvas or other objects.
These make a very special gift for grand parents or those who have lost a person.
