Surprised Sousaphone pony

from the episode "The best Night Ever".
Bluenote aka Beauty Brass aka Sousie Tuba getting caught from behind by the excited Pinkie, at the Grand Galloping Gala.

it wasn't very easy to work on this since the reference picture was small, plus i'm not enough familiar with Illustrator. but i hope it's good. let me know if there is some errors.
