Here is what Celestia looks like as a centaur.

If they didn't use the EQG style for the Human half, this would have been pretty interesting.

This is pretty neat.

I would have preferred that whoever did this used a more original fanart humanization rather than the EG version for the human half, plus the pony half looks pretty small compared to the human half.

That is true. But it could just be the angle of the body.

7910736 I feel that the horse part should be bigger.

Also, real centaurs don't have wings or horns on their bodies either even though centaurs don't exist in real life.

7911053 I'm just saying that anatomically the size of the pony seems small, making her very top heavy. Assuming that she didn't just topple over all the time, this would put great pressure on her spine.

That's all I'm saying. It's not meant to be insulting, merely to offer insight and to encourage growth. We all have room to grow and the day we stop growing is the day we die.

Now that I think about that, it might probably make it hard for them to walk considering how unbalanced they look.
