Among the Jabberwocky Graphix publications were some of the early minicomic format booklets, ranging from the standard 8-pager up to the thick, 375 page "One Year's Worth".

For that comic he was listed in the credits as the "Big-Background Artist", which referred to his role in both penciling and inking the larger and more detailed background designs only on certain select panels and pages, rather than throughout.

Since 2010 he has written and drawn the monthly cartoon "The Funny Business of Art" for Sunshine Artist magazine.

Foster has won multiple awards for his artwork at various art festivals and conventions around the country, including twice at The Red River Revel in Shreveport, Louisiana.

Foster was the artist guest of honor for the 2010 NASFiC, ReConStruction,[12] Conestoga 9 in 2005,[1] and Archon 35 in 2011, and Sasquan, the 73rd World Science Fiction Convention, in 2015.
