Slow Motion Lefty Pitcher Video Advice?

I’m 15 and I throw for South whidbey high school, I am 5’11" and i weigh 145 pounds.
Any advice on my throwing mechanics would be great

too dark

I don’t really want to comment since there are some things I think I see but the video hides it so much, can you lighten up the video, or upload a different one?

looks decent. get the hips/butt moving towards the target sooner and you will see more velocity.

watch the hips/butt movement between 20-26 seconds. by the time Roy Oswalt is at leg lift his hips have slid over quite a bit, increasing body speed and stride length.
