I actually use the same program, psp7 but I do it at 400% scale then resize it, before I used to do it at 100% scale. One thing I don't like about psp is the way the vectors' edges are flat. (Which is why, at 100%, my characters have faults) I really gotta get used to photoshop some day.
Here's what he looks like at 100% scale.

Welp, it's your guys's choice as to whether or not I work on a better looking version of my characters. Potentially, brad could just remove the old kaddar character's catagories and put in a new kaddarDX directory, meaning old comics would retain old characters (unless edited) and new comics would have new characters only.
