Quit thy whistling, or else...

This is the first critique i'm writing, so... bear with me.
First of all, i want to say that this is a wonderful drawing! You got the shading and the lighting very right! And i noticed little details, like the little crown details, their mane sparkles, or even the mug and the bow, that make the artwork more... funny, if you know what mean.
Now, you have a really good technique! I know it's not that easy to make all of that with acrylics! You are really good with it!
The impact is lower than the others because i know this is not suppoused to create some emotions, but it's to be fun.
In the originality, in put that rating because, it's obvious that it's MLP, but it's a really original picture, something i've never seen before, nobody had this idea ^^
Very well made artwork you have here!
