I'm curious about the step in which you flip the composition? Where you considering flipping it, or is this just a review of some sort? I know when I flip my work, it looks wildly different to me... I presume because of the way I lean across my tablet... and I wonder how it looks to others? Great piece, by the way!
I don't know the exact number of hours I spent but I worked on it here and there over three weeks. Well at some point I lost motivation and focus But I just kept painting for the sake of getting it done.
