Are there any differences between your waifu and the canon version?

[Lurker]

My Twilight's wings are larger. All wings are larger than they are in the show.
She's a metalhead, and will cuss in casual conversation. Not at all what I expected, to be completely honest.
She's a tad absent-minded about a lot of things. Very focused on her work, not so perceptive of her friends.
Twilight's still very amiable, though, and a good friend.
Her mane's a little darker.
Her voice is a tad different. I'm not sure how to explain how it's different, exactly, but it's a little different.
Twilight isn't excitable at all in the morning. You could practically tell her the world's ending and she won't flinch until she has some morning coffee.
She has armor, being a princess. She only wears it on occasions.
She's not an Element of Harmony. The Elements of Harmony, as far as I can tell, don't exist.
Our home is still the library. It's much larger on the inside.
For that matter, I'm not sure Tirek even exists either. Even the common changeling consumes magic, so Tirek's power is nothing original there.
Twilight's pretty adventurous in many different ways, from areas of knowledge to exploring the world. I suppose that's actually the same... but she's more curious and less 'we have to do this because x says so.'

I think that's enough of a list for Twilight, but before her, I was with Rarity, and before her, Roseluck.

Rarity's got a little bit of blue in her coat. She still looks white, but in the right light, you can see. It's very subtle, kind of like the pink in Princess Celestia's coat.
She snores like nobody's business. Like... wow, it's loud.
Some friends of mine do model work for her.
Spike still has his weird infatuation with older mares. It's somehow less awkward between them, though. Little more friendly, but you can tell how Spike really feels.
Rarity's six years older than Twilight, and three years older than me.
She's still vain and manipulative here or there, but nevertheless generous of possessions and in spirit. She's also something of a tease.
We actually met after I got a stallion who was berating Derpy to back off. She thought it was 'noble' of me to 'defend her so valiantly.' Really, I was just correcting the guy. He was being an ass.
Rarity might have a dangerous curiosity for dark magic.
She lives on her own.

Roseluck's kind of superstitious.
We met because I decided to trot over and start talking with her, because I thought she was cute. Which she is.
Botany is kind of a big deal in Equestria, since plants are used in everything from alchemy to cooking. She's a pretty smart mare when it comes to cultivating magical flowers. They're all magical, but some more-so.
Otherwise... she can be pretty silly. And, by silly, I mean stupid.
She's nice, though. And did I mention she's cute?

Before that, I was with another gal in my other wonderland, and had some on-off casual no-commitment flings with some others. Not gonna bring that up here, though.
