Dude, he I was all pumped to see a video, I went to click play and realized it was just an image.
Tough to tell from just one shot to be honest. Although what I see does not look bad at all. Looks like your fairly well balanced, follow through looks like if it continues it will be fine. But like I mentioned, just a snap shot is really tough to tell. If you could take several shots and post them in a row that would help too.
