*ahem*Let's get started:
AJk.The neck is a little fat though.And her front hooves look a little short.Other than that I like her expression.
Twilight:Her neck is also a little fat.Also You put the cutie mark on both sides.I'm not sure if that's what you were going for but still.I like how her hair goes up but I think she needs a little more expression.
Fluttershy:Her neck is a little thick and her wings look curved in a way.The snout looks a little weird too.But other than that it's fine.
RD:The neck is wee thick and the chest looks a little "Big".
Also the hooves look a little deformed.But the expression is priceless!
Rarity:I really like how you did the pose.The hair though would've been more flat though.
Pinkie:Can't say anything about this but awesome.
Vision:I can see what you were going for.
Originality:I've seen tons of others do this before but it's nice.
Technique:I like how it's drawn.
