I watched the one where he wouldnt move. First of all, keep your hands down, I dont know what your trying to acheive holding your hands up high. Second of all dont worry about his head...just yet. Therefore when asking him to walk on, dont drop your hands. Put your elbows forward and say "walk on" if not kick him. He is just confused, so leave his head alone.
He is coming up nicely from the other older pictures i have seen of him.
