The only thing about it that looks "off" IMO is that the windows and shuttlebay doors are placed a bit too close to the top and bottom edges of the saucer, making the ship look like it's hull has no thickness. The front shuttlebay for example seems to be leaving no usable space for rooms behind the windows directly above it.
