Hi Casej,
Looks like quite a good "1st attempt" - congratulations. Nice clean and simple setup too I might add. Going with the Rogue was a particularly good choice and good value for money.
You may get some benefit from moving the Maggies a bit more out from the wall if possible. Aside from that, not sure that I would be replacing anything and, rather, might think of adding a subwoofer. Of course this depends on whether you deem it necessary and/or are happy with the sound as is. If you do ending up considering it, a nice fast sub akin to a REL, Velodyne, MJ Acoustics, ACI, etc., would likely suit your Maggie's quite nicely.
That said, take your time and enjoy what you've got.
Happy listening,
Garry
