The thing that always bothered me was that we never saw the surface of the DSII from Palpatine's spire (I mean it wasn't that high up from the surface in the first place - so I could never understand why they never experimented a little bit more with it in the two Special Editions). I love all your mock-ups of his Throne Room looking out at part of the battle station and at the wonderful new starfield you've added. Would it be possibe to add a couple of TIEs sweeping past his window, or is that a bit too much? (Though actually in the shot previous to this there were some TIEs that went towards and around his spire - so it'd add some continuity).
EDIT: And my oh my, you have indeed added life to that set.
