I think overall it looks better. It represents overall color schemes in the entire cover image better (by much lower magnification) than the previous algorithm which sometimes looks irrelevant to the cover when it's magnifying an inessential area. Also the patterns and color tones are more homogeneous without many anomalies. To some extent, it could feel a little boring without much variations. But it would work better in most cases.
One thing you could improve is it currently only magnifies central area of the cover by going up and down. Maybe it could show outer areas as well.
If possible, I'd like to have more control over the function for TM: blur intensity, magnification power, interval, etc.
