That Jason player let you get away with murder. >.> He didn't punish you for b14 on block, he didn't armor through the gap during b14 into Sun Choke or EX pizza.
Not saying you're bad, but he was clearly a waste of your time. =P I haven't watched the matches yet, but I'm gonna.
Also, parry the hell out of those machetes. Use b2 more often during the neutral and/or oki.
Upon watching more matches, I have some other suggestions.
For one: you're using f12 as a punish instead of doing f1b2. You lose out on a lot of damage like that. Work on punishing with the following combo: f1b2 > s1 > f2 > b14~db2.
If you think your timing is gonna be off, use b12~db2 instead. The difference in damage is negligible.
If you can make your opponent respect you, stagger f1. I like to do f1 and then f1b2 if they tried to press a button that was slower than my f1. It doesn't always work, but throwing it out there now and again can be rewarding.
