Warning: Kind of spoilery to Past Sins
So, with the changes done to Past Sins for it's Season 2 upgrade, one part that changed was how Luna was portrayed. In the original version, Luna went from what we see of her in Season 1 to something close to how she appeared in Season 2 in the final chapter of the story. Honestly, it was kind of cool at the time to see canon Luna did go through a growth spurt similar to what I had described in story.
Still, with the Season 2 update to the story, I now had to start with Luna as she was in Luna Eclipsed and make her mature again to something closer to Celestia. Personally, I don't see it as a far stretch as something that could happen, but describing it was a bit of a challenge at the time.
Now, you may be asking why I bring this up at all. Well, I was checking EQD's drawfriend today, one of the images featured is just too perfect. It fits very closely with how I pictured Luna becoming if she were to go through another growth spurt and become more like Celestia. And, so I decided it to share it with everyone here real quick.
Now, to clarify, this wasn't a request or commission or anything like that. This is just a happy coincidence that I decided to talk about and share. So, for those who have ever had trouble picturing Luna as she was at the end of Past Sins or during Winter Bells, that's picture up there is darn close to how I personally imagined her to be.
