Pillows look a lot better now with colors, but I would probably lighten the brightest color to near-white or hueshift toward blue because the pillows look more like sandbags now unfortunately, and blend in a lot with the rope (perhaps too much.)
Aside from that, I really don't think a motion with this many frames needs a motion-blur -- it looked great without it.
If you really want to get that blur in there for a 'pop' sort of action, you'd be better off using a bit more lag before the downward motion, and that downward motion would be maybe 2 frames, tops -- one frame with the blur of the entire motion, and the next with the head settled where it ends up. You might also want to convey that blur with more of an actual 'blur' look than the spiky look you have now (spiky generally conveys rough, 'textured', movement through the air like when swinging a broom or hair to attack, whereas straight/rounded blur edges convey a switft/blunt motion through the air.)
You could get that same 'pop' in your motion by reducing the frames in certain places however, so aim for that first -- and if you're still missing something after that, feel free to use that set of frames as your starting point for a blunt blur of around 2 frames or so before the head shakes.
