Research and development - Tracking shot development

I personally felt my original tracking shot was decent. However, i didn't feel it suited the intensity i wanted to capture. In my film, i wanted to express a more dramatic sense of fear than having Lucifer slowly approaching the victim. On Movie plus X6, i edited the play speed under General which sped up the film creating a more dramatic effect. An example of this is shown below.

This was 3 times the original speed and I felt that this was sped up a little bit to much. I felt this high speed reduced the quality of movement as it looked a bit too fake. so slowed it down to find the right balance which is shown below.

I felt this was a lot better as it looks as if Lucifer is rushing, but the victim is still unaware. Furthermore it hasn't damaged the quality of the clip which is an essential factor which makes it the clip i will use in my film trailer.
