Not for me to judge your stuff mate, i learned using your vids...but i think it looks a little sad, depressed even.
I notice a neutral pose is allways the starting point on a lot of charactors and animals etc.. this presumes that you have to rig good enough to get the pose you finally want, why do you not start out with the heroic pose, then just model that?
Your work allways displays skill and determination.
