One of the things I have discovered in my edits of Starforgers is that my villain, Kantor, needed to look more distinctive. In my first draft he was pretty much a typical looking Votainion. Blue skin, pronounced browline, goatee and jet-black,long hair. The character was fleshed out by what he did and how he acted, not so much in how he looked.
But situations in the novel, which I won’t disclose, made it necessary to describe him in a way that would bring out some unique features concerning his face. What a wonderful opportunity for back story and description. So of course, I have to go back now and rework his description and that will also have to be tweaked all through the novel. But I think in the long run it will be worth it and the character will be more complete for it.
