You make good pose but i notice two mistakes.(so sorry now for the bad english now)
First the head of many of your characters (or sometimes body parts) are too small. Like Shiftrunner or the last.
Second. Sometimes the transition from a body part like the shiftrunner picture is wrong. So it looks like he grows from the middle of the chest( as a example).
You can use small black circle or a rectangle to fix it.
So i hope you dont understand, i like the picture, but i think critique is good to make it next time better.
