OK, I have to say that I'm not so keen on Valdesi's interpretation, but I can admire his athletic ability.
Regarding your Gankaku, and commenting on your performance, and how it differs from a "standard" (if there is such a thing...), I'll offer the following:
The opening move is usually done slightly differently than the way you do it. Rather than firing the X-block from the hips, the hands come from the lower right hand side and end up all the way across the body on the left.
The shift left into kibadachi after the kakiwake uke in front stance is normally done by stepping back with the left leg, rather than forwards with the right.
I would also suggest that you should be in a sidestance after the middle two side kicks - where you're doing the hook punch.
Finally, the rising elbow strike near the end would benefit from more drive, like you would do in a reverse punch, closing the hips. I think Valdesi's performance at this point is particularly lacking as he sacrifices (and it's not just here) power generation for show, IMO.
I think Kanazawa's performance encapsulates most of these points, although there are small differences between his version and standard JKA. You can see it here: Kanazawa's Gankaku
As I say, these criticisms may only be relevant if you're not already aware of these points and have chosen to do your kata another way. If the kata is for performance and aesthetic appeal, you're going to have as many differences of opinion as you are replies...
Hope the above is of some use however, and kudos to you for putting your kata up for all to see.
