Awesome job on this Aklimovich!~
Constructive Criticism (I can't color anything other than vectors right now, but I'll give my opinion from an artist's standpoint):
The front of Pinkie's mane needs to be a bit "poof-ier", not sure how to word that.
The ear could be tilted back a bit more, at a different angle.
I'm also not sure how to word this, but look at the neck (around where it joins with the head). The way you colored that looks a bit off to me perspective-wise. The neck should fuse with the head towards the back instead of having a line seperate the two.
Gotta love the tear though
