Which one one of the videos is the one that you prefer? (I liked the animations in the video about mars. They start at the 4 minute mark.)
Anyway, since you have a few old videos, I recommend to post once per week so people don't complain that you post too much. And then post the new videos when they are published.
Also, people here is sometimes interested in how things are made. What program are you using to create the animations? What program are you using to create the videos?
