These are background Ponies? Strange, I don't recognize them... And here I thought I knew all the background Ponies already. They look pretty cute, though I wonder why the commissioner commissioned these two specifically.
Actually, it's because I'm working on a story about them. Symphony only appears for a few seconds in 'Sweet and Elite' with Octavia at the garden party, and Sea Swirl is actually a constant background pony, it's just that she gets very little attention from the fandom. So, I'm going to attempt to change that. I even have plushies of these two on the way.
The yes! Just...all of the yes!!!!!!! And you got Symphony's bow tie in there as well. I love Sea Swirl's eyelashes, and the blush on Symphony's cheeks, and...I'm going to stop talking now because this comment is going to just become rambling gushing of praise.
You should submit this to EQD if you're comfortable with that, because it is simply that good.
