I still go back to my old Betty and Veronica comics. They're marvels in pacing, layout, expression, and simplicity. Great stuff.
Another creator described Groovy, Kinda as "Archie Comics for adults." I was very flattered.
Right now I'm plowing through "SPQR Blues," a soap opera set in Ancient Rome. Well researched, nicely drawn, with a dry sense of humor that I love.
Other non-Tapastic faves are Princess Chroma, M9 Girls, DadRockGirlPop, Bohica Blues, and Doodling Around.
