Well, first of all, you need to warn your viewers that you will be landing on some drier ground past all of the mud. There was quite a bit of pucker factor while you were flying over that swampy ground. I was really anticipating a nose-over in the glop!
I have a couple of comments. First and foremost: if you're practicing short-field technique, then you need to practice touching down at the threshold. I don't know exactly where the threshold was on your landing location, but I'd say you overshot it by almost a hundred yards.
The landing itself looked pretty smooth.
For a soft field like that, I was expecting to see the nose come down farther down the field. It looked to me like a pretty flat landing. I would have had the yoke pulled all the way back into my lap at touchdown and held it there during the roll out. That minimizes the weight on the nose gear until you get slowed down, which is important on soft ground. It also gives you more weight on the mains for better braking control. As your speed decreases, then your nose will come down, unless you give it some throttle to increase your elevator effectiveness. You might have been doing that, I couldn't tell from the video.
How were you using the flaps? The glide slope looked about right for a normal runway. I would have expected a full flap landing for short-field practice and that a steeper glide slope would have resulted from full flaps.
