Sometimes there are ideas that you execute but for whatever reason it just did not turn out how you imagined it in your head. Some of those ideas just needed to get out and weren't really that interesting (i.e. sucked to begin with) but...some you just keep thinking about. "How would I have done it differently?"
'Arsenic' was a piece I created back in 2008. It was really never "there". I've been wanting to rethink it since I completed it and I finally have the time to before I start in on the new series. I'm definitely enjoying the progress so far and hope to find some closure with this idea in the end.
