Put down that fork, it isn't done, just "on hiatus"
It isn't done until YOU say it is, morikhan! Have faith, someone may come along with time, talent and a shared vision of Old Wizard to keep it going. Put the word out in your circle of webcomic enthusiasts that you're looking for an artist.
If, in the worst case scenario nothing more is ever made for Old Wizard, know that I cherished each strip!
