Any thoughts on my technique?

I wonder if any of you would give this video a try and let me know if you see any major problems with my technique? The angle of the video may be awkward, but I hoped to get a side view so that I can keep track of any wobble. also, that's the only way I can position my iPad without some special mount or something :tooth:

Be honest, but be gentle :wink:

I don't have time right now for a full watch and other people have lots more experience then me but the quickest things I can say is: use the whole stone. Either use the whole stone or every once in awhile flip it 180 horizontally and give the back end some use. (not so much a critique on technique just something to keep in mind)

something I also forget to do a lot which at times it looked like you were doing don't forget to lighten up the pressure when progressing through the stones.
