all were pretty good! a couple tips that I'd give are:
Avoid having people in a timelapse of clouds. Don't know how well that makes sense, but if you were to take a cloud timelapse it would be sped up much more than a timelapse of people. If you are doing a timelapse of people, for instance in a city, its fine to have clouds, but the speed will probably only be like 400%. The clouds would move slightly faster than normal. If you were to be speeding up a timelapse of the clouds over a field, you could speed it up to anywhere like 30000%. in this situation though, if there were people in the field, that could look really bad because they are moving waaaay to fast and just jumping around the screen. Thats the best I can explain this phenomenon, and i hope it makes sense.
(I don't know what you're shooting on, but when i say speeding it up, that could either mean setting the intervalometer to shoot at a slower rate on a DSLR, or speeding it up after shooting a video in editing software.)
Try a slower shutter speed on the creek shots if at all possible. it will make the creek look really smooth (this really only works on DSLR,and you may need an ND filter to do this.)
Obviously these were all shot by your house, but the more variation in location the better the video will be (as long is its not all over the place).
I personally like to have my nature timelapses have absolutely no sign of civilization (e.g. no buildings, roads, etc.) and then if i want to have civilization in my shot that is the focus of the shot (like in a city). that being said, this is 100% personal preference and thats just what i like to do.
Lastly, I wasn't huge on the shot with the bees by the flowers (the one through the window), because the bees were really flying too fast around the frame.) maybe slowing that would help. again though, this is personal opinion.
anyways, that was some good work! and i am not hating at all with these comments, just trying to help!
