OK, so on the main version, you've used the stems, but left out the keyboards, yes? I think you've also made the drums slightly bigger, but the guitar sounds lower in the mix, and also quite flat and one dimensional. How are you mixing the stems? Are you mixing, for example, Guitar (1) and Guitar (2) together in one channel? Only, they are supposed to be separate, as left and right channels - that's what makes it stereo. I wonder if that's why people comment that a lot of your mixes sound like they are mono?
The 'extended' version isn't bad, but doesn't really add anything to the song, and the long gap between Freddie's intro and when the guitar comes in sounds out of place. I would have done it something like in the attachment below.
