Is it postwork if you are using a newer version of software with more features? Those added features are postwork to someone that has not upgraded yet. I do understand the artistic and intellectual challenge of limiting yourself to a certain set of tools but software's capabilities are a moving target. What is currently postwork may not be with the next version upgrade. Ultra Fractal did not always have the features of the current version. I guess we would need separate galleries for each software upgrade (not!).
