Old vs. New Twilight Sparkle

I bet most bronies/ pegasisters can agree on this. That, they rather stick with Unicorn Twilight. And I guess can agree on that, but I don't hate Princess/ Alicorn Twilight. I mean, she sometimes have the same character, but whenever Twilight is teaching Starlight, than yeah, that's where I have to disagree. That's where I have to say Twilight shouldn't be doing this. I didn't make this because people can agree that old Twilight is much better than new Twilight, I just made this because...well because I feel like to.  Again, I don't hate Alicorn Twilight, but I think her character doesn't really fit, in my opinion. Alicorn Twilight was pretty interesting in Season 4-5, but I didn't like her as a teacher and her character in Season 6 and I guess Season 7.
I have trouble making the background. Same with the mirror. And the shading was pretty hard.  
And this only took me 2 days.
