I think the idea is very promising. As someone who really enjoys ASMR, I can definitely see myself spending time with such an experience.
On the flip side, I feel that it definitely falls a bit short of its potential. For such a limited scope, the positioning of the images and links (and overall user interface) could have been more polished. There is also room for improvement in the way the sound presentations are structured.
Overall it was an enjoyable moment to relax, and I would highly encourage further development ^^
