ABSTRACTION TO REALISM: OIL & COLD WAX.  Have you considered combining oil paint and cold wax?  The addition of cold wax medium into oil paints not only allows you to create beautiful texture while speeding up the dry time of oils, but is a great solution for oil painters who enjoy working realistically while allowing expressive and abstracted elements to be incorporated into the painting. You need not be an experienced oil painter, but a basic understanding of working in oils is important.
