Alas, I fail to see much merit in Freud's work aside from that he painted subjects in a largely representational manner. After due consideration, if I had to characterize his works using one word, it would be: Icky.
As for his early works, they too were essentially representational, though shapes were simplified and distorted to one degree or another. The following images were found on a BBC web page.

For some reason all three of the above portraits feature heads where the part above the eyes is compressed.
