Collecting feedback for the edits to make on my intro footage- ( polled to appear before my root menu)

I had gained many ideas of possible edits to carry out some of which I have are:

Edited in Adobe Premiere

1.) Slowly increasing the speed of the images appearance and exit (so they enter and exit quicker), this would build up suspense, (along with the background music.)

I carried out this edit, exported it as a video and posted it on Facebook, to collect qualitative/ detailed feedback. Overall the audience felt it didn't work well with the slow suspense background music. As the images slowly increased in speed, they felt they weren't able to reflect on the horror/ scary imagery.
I also tried increasing the speed of the music to match the timing of the increasing speed of the photo slide show- this was not approved by the audience either.

 So I gave the photos a consistent timing along with consistent animations. The audience felt this had more of an impact on them , as they were able to actually 'see the images'.

The audience also like the white flash (shortened dip to white transition)  as this adds a dramatic effect to the ending of the slide show, which is also well timed with the music.
