Swing

I am 15 (I know a little scrawny for my age) and a freshman in high school. This is just a dry swing but any help would be appreciated.

it would be nice if you actually swang like you meant it, that looked at about 75% swing, swing like you mean it so we can actually tell you, it looks like your going through the motion, and I wont say anymore till you post a real video, anyway what are your height/ weight?
