Hey there,
On a different DA account some years ago (which no longer exists), I was a fan of your work and your comic series (which I'm saddened that it never really took off).
I don't quite know what the whole drama was or the story, i'm sure it's really non of my business, but just because some things didn't work out, doesn't mean you should give up completely.
I thought Tacky was a rather interesting character, she kinda reminded me a little of Deadpool and Korosensei, though her motives were a little more selfish (IN A GOOD WAY! PLEASE DON'T KILL ME!).
I know it's not up to me, but I think personally you should come back and bring Tacky back. Rather then runaway, why not re-start the whole thing over again. Re-look the character and the possibilities. Add new characters or change the story and setting. Make a whole new plan.
But it's entirely up to you and i really hope you'd consider it.
