Does anyone know what manga/anime is this image from?
or is it just some kind of a cover drawing for yuri magazine thingy..

It's the cover of the Yuri Hime issue. http://dynasty-scans.com/issues/yuri_hime_vol_26

Pretty sure it's a stand-alone illustration, not connected to an actual series.

Yeah it's just the cover, no story connected to it. 99% sure of that.

^As the video shows, there's an art book for that YH cover, entitled "Girls Uprising : Novel and Illustrations" by Kazuaki (art) and Makoto Fukami (novel)
