Vodka- OC request

here it is! ^^
in my (modest) opinion, this is my best work so far! i absolutely LOVE this coloured-lines techique!
that's a request from VodkaHorse (http://vodkahorse.deviantart.com/). she asked me to draw her horse Vodka dancing with glowsticks...
i've been asked this a long time ago, but i had so many requests in front of this one that i couldn't even think of it.
this one took me a few hours, i had to re-line it with coloured lines (the easy part) and to colour and shade it (the nightmare). but i think it turned out pretty awsome!


hope you like it, comments always welcome!

---------------------------------
time taken: 3 hours (plus 1hr for the original sketch)
reference: none, actually. i've just looked at the ref-pic to see if the proportions were those of a "regular" horse.
media: i've doodled around with it for a while, but this one was made out of nowhere, with photoshop and tablet.
