Sometimes it can be very useful to revisit an old work and do it over again with your current skill set. My fly girl (inspired by taking people literally when they say "that girl's so fly") is a visual pun from 2014 that continues to be one of my favourite ideas to date. I decided to give her a 2016 makeover with my improved abilities and I'm really happy with the clean linework I produced.
It's been quite some time since I've gotten so absorbed in drawing that I've lost track of time, and even longer since I went from a sketch to clean art in a matter of hours. I've been happier with the quality of my present body of work, but I've sorely lacked the speed I used to have two years ago. On the other hand, perhaps taking more time with the process has produced the quality of linework that I can do now. It makes me look forward to the years ahead and the improvements that I'll have made by then.
