First, I'm noticing a lack of jump height. Second, you're using your hand for balance upon landing. Third, only ten seconds passed after the first side-slip, which was slightly worse, due to leaning forward, and less than ten before the third, which was honestly terrible. Lastly I notice you're not holding your landing posture.
Reference:
1: Jump higher and reach out more, before arching.
2: Don't use your hand at all, this could cause wrist injury.
3: Rest up more between each run, or you're going to get progressively worse due to over-practice.
4: This can result from lack of precision, or lack of landing practice, by the looks of it, you're not absorbing enough impact + momentum, which is causing you to continue movement even though you don't want it.
