Really nice for you first walk buddy.....

Things to look at....

1) needs some more rotation in his hips and shoulders

2) add a bit more up down as he walks. When his feet are apart that his low point and when hes steping and feet are together, that his high point...

3) the shoulders seem to fall at the end of your last step.. just but them back up..

that good for now, just watch how your feet move and rotate as you walk...

Great work buddy.. you have come a long way in a few months...
