If you're going to do the dynamic start that's okay as long as it's comfortable for you. The only change I would make is make sure your eyes are straight ahead instead of looking down when you pull the bar off of the floor.
On the jerk, your back foot is turned out and almost flat on the floor. Try to stay on the ball of the foot and keep that toe straight ahead or even turned in slightly. Think about keep your hips square on the split.
I agree with Charlie, you can widen your grip so the bar makes contact higher on the thigh.
