1-the shot is blurry but like you said, having the cups farther apart should fix that. also the edges of the hood are the more stable part of the hood, its kinda flimsy in the middle. so having the weight more spread out and the cups on the more stable part of the hood should fix that.
2-the background man, the blur isnt very pleasing ya know. the background for rig shots are just important as the background on static shots. try an open area where you can get a cool sky or next to building that has doors, windows, pillar, whatever that will blur.
have fun, rig shots are fun stuff
