I have to go to work soon

Reference was found on Pinterest for these first two

These next ones I looked at panels from Arzach by Moebius to steal part of the pose. I rarely copy any other artists but think it might be a good thing to do. Not for the sake of stealing, but learning. After this exercise I'm feeling pretty rotten about my art. But that's good, because it means I have room to improve?This is probably going to be a formatting nightmare using all web browsers so I apologize.
