Oh laaaawwwddddyyy. That took FOREVER. I only finished this because I'm running a fever and have stayed in my dorm all day. If not for that, you probably wouldn't be seeing this until tomorrow or the next day..... I'm surprisingly artistic when I'm sick, which is good for y'all I suppose.
A quick word about the file itself: If you download, be aware that the file size is larger than ANY other I've done so far. Approximately twice as large, in fact. Blame the mane.
Now that that's out of the way, lets talk about the wallpaper. I was unable to find a unique NM vector that was up to my standards. So, I made one..... sorta. I've been calling her 'Frankenmare Moon'. And this is why (tl;dr ahead).
After getting fed up trying to meet my own standards, I broke down and did borderline art. For the body, I flipped the Celestia wallpaper and adjusted other pieces to match the size and position set by the former's base. I found a good NM vector and used that for the head shape, wings, and cutie mark. The mane and tail..... lets just call them a hybrid. (The sparkles are all from the Celestia wallpaper, though, just recolored, repeated, and flipped a few times. Basically, its the Celestia sparkles 10x over xD)
I used a piece of artwork I found that had NM's mane in flat color as the primary shape. Additionally, bits and pieces of Celestia's mane and tail were used for shaping as well. The rest, like some of the 'curls', were done by me. But the vast majority of my intervention was done on the tail; I'd say about 2/3'ds of that tail is my own original work. So if it came out badly, let me know and I'll try to learn for the future.
I wanted to make NM a 'mirror' of the Celestia one, so that multiple monitor users could benefit. Incidentally, if anyone would like me to repost the Celestia and NM wallpapers with flipped images (ie, Celestia on the left and NM on the right), I'll be happy to do so. I'll only do it if asked to do so, though.
