Easily yes, I feel I'm getting faster and my line work is getting faster. When you're drawing comics, you don't really have a chance to get emotionally attached to your drawings or get fuzzy about perfection because you have so much to do in little time. When it comes to doing promotional images not affiliated with a comic, I do slow down a bit more for quality, but even those I feel I'm getting better at and am getting faster and better.
But I also feel I have a lot to learn and the journey ahead is long and difficult. I still want to learn some techniques to go faster and make crispier inking. But again it's all for the future.
