'All-Star Wonder Woman' would get worked on in what is laughably referred to as my 'spare time.' I just ended up with less and less time to devote to it. Eventually, we all realized that it was taking forever, so we just all agreed to hold off on it 'til the time was right to do it properly. Well, I still have a contract; DC never tore it up.
Color always vexed me because I would fight with the media I was using. I love coloring in Photoshop, and it's freed me to pursue ideas and techniques I wouldn't have otherwise attempted. Since I get to take an assignment from concept to final execution, I have more freedom in my idea-making processes.
