We even got negative feedback about the shadows for images from users who work a lot with icons and other images which have a lot of transparency. Shadows make less sense for this kind of image than for, e.g., photos. I think that adding shadows to video thumbnails might make sense though - thanks for working on it!

Ok good point. But what about shadows for documents, e.g. PDFs or ODTs? 
I think shadow also makes sense in these cases.

IMHO we should apply shadows to all different kinds of thumbnails and only exclude icons and other problematic types.
(Example - other FM with shadows on documents: http://www.stboston.com/wp-content/uploads/2013/10/Mac-OSX-Finder.png)
