Artist intended it as foalcon.

Something to note, taking into account The Journal of the Two Sisters: The Official Chronicles of Princesses Celestia and Luna byt Amy Keathing Rogers, Celestia and Luna age much more slowly then other ponies. While they were without cutiemarks when other ponies had long had theirs, they are also older then any of the founders of Equestria when they met.
 
So really, arguing foalcan really doesn’t make much sense if you understand how the royal sisters age. That is, unless you want to call foals of ponies older then the adults of the other races.

@Aucky  
Fair point.  
…having said that, let’s just enjoy the view.  
mh

@LunaticHell  
By that do you mean  

Plus, that belly bulge looks sooooooo haut :))))

@LunaticHell  
I’ve read she and luna got their cutie marks really late in their life in comparison to the rest of the ponies.  
So this is prolly when she was about to enter adulthood or already did.  
Also, comparing human lifespan timeline to a cartoon character’s whose plot states that has lived for more than 1000 years is not accurate.

@Goblinette  
I’d say between 8 and 12 years old, considering that I suppose Celestia was one of those mares who grew big rather early.

Fanfic to go with this.

Breaking our young little princess in~ how yummy.

@LunaticHell  
She’s obviously younger, Hardly a filly

@Goblinette  
I guess by the look of celestia, this must be her way-way-way-way younger self from way back when she was a teeny tiny cutie pony. yum yum  
Note her underdeveloped boobs.

@Background Pony #0CDA  
+1 on this.

@Goblinette  
That’s what it says, according to the source.

Foalcon? Where?

Seriously I want a comic to go with this. Please.

I was wondering when this one would get colored!
