[11][12] He penciled five issues of The New Teen Titans in 1985 and writer Marv Wolfman later commented that "I knew that I had this incredible artist who could draw almost anything that I wanted...So I decided to make the story just the biggest spectacle I could come up with.

[14] His work on the Cinder and Ashe limited series was praised by ComicsAlliance in 2014 which noted "His characters are never in a static position; they’re always stretching, or crunched up, or twisting.
