According to other Derpibooru comments on this artist, we’re getting serious lolover vibes.
 
Doesn’t hurt that the pony being drawn most often is Twilight.
 
However, the handwriting is different from the Sketchy Twilight Sparkle’s handwriting. So unless lolover is having someone else write his text (and/or could write in Korean before but never did for the Sketchy Twilight tumblr in addition to perhaps being French,) I’ll just guess that it is a particular style that they both picked up on.
 
Or that black dog was inspired by lolover.
 
Either way, it’s quality stuff. I dig it.
