Here it is! The 1920x1200 variant (which should work on 1680x1050 monitors if you're using Windows Vista / 7 and using the 'Fit' option).
Added editions are:
Night Mare Moon
Bon-Bon and Lyra
Twilight and Trixie
Twilight Sparkle (Variant)
Note: These aren't EXACTLY like the originals, because they were designed for the 1680x1050 monitor, and I wasn't expecting people to want a 1920x1200 edition. So these are remakes, if you will.
The original 1680x1050 versions are included though.
Also, for the display picture..
