I think the life drawing practice pages are particularly interesting. Like the one with the belly dancer, how you use shading to show her stomach going in and out. Also, the notes are interesting. I've been signing and dating my sketchbook pages, but I hadn't thought to write how long it took me to do the drawings on there (example: 1 hr., 5 min.).
You did a great job with your Empowered world ! Love it, but because I am french I miss your comics in french version. It stop at the 4 volume. I tried to read the english version but I not always understand the jokes when there are crossed with neologism or word games. So I lose some fun. I hope the french version will continue. But it was stopped couple of years ago. However, maintain your nice creation on top, it's a pleasure to see.
