The new carrier looks good, but there are problems with having a rotational section, especially one that large in relation to the rest of the ship. Torque and gyroscopic precession.
With only one rotation section, the rest of the ship is going to spin the opposite direction unless thrusters (or handwavium counter-torque device) are constantly counteracting like a helicopter tail rotor.
To counter the torque and gyroscopic effects you need an equal mass spinning the opposite direction at the same speed. Alternatively you can spin a smaller mass faster. 1/2 the mass at 2x the speed, unless the math is more complex...
For cases where more extreme maneuvering is required, lock down all the spinning stuff or you'll be beating up the bearings from stress. Darn gyroscopic forces, while canceled out overall will still strain the individual rotating parts.
The only movie I've ever seen with a ship that had dual rotating sections and did things close to right was either Red Planet or Mission to Mars, both from 2000. They both stank up the theater, I don't remember which one had the somewhat properly designed ship. Both had soooo many instances of horribly bad science fails.
