Definitely an interesting comic. It made me laugh, that's for sure. Though I'm not really a fan of your style, I have to say that you did an excellent job in illustrating the ponies, and especially the backgrounds.
As far as your style goes, it's a definitely distinct one that works well for Western-style cartoon comics, even if it's not anything remotely similar to the show. The curves and over-deformation of the facial features help to effectively apply comical situations, especially in panels 5 and 6.
Most of the comic's writing and story really give a WTF feel, especially panel 3, with the sudden Rainbow Dash cutie mark. Personally, I don't think it really works, just being plastered on top of the panel like that. Maybe you should have added some more rainbow explosion effects onto the foreground to make it look like it's part of the scene, rather than being on top of the scene. Of course, Pinkie's button eyes help to supplement the humor of the panel, which works out in the end, I suppose.
Overall, it's definitely an excellent comic. 4.5/5
This made my day, It just did. Aside from the style being so perfect, adding that cartoony feel this comic, the idea and how it is executed is so greatly done! This is excatly how both would react, Rarity all out petrified while Pinkie is having a good time! Pinkie's Randomness is something that always comes in handy, when doing comics, of course. It just adds a layer of cuteness and comedy that goes hoof-in-hoof (ha!) with the show. Can't forget the Lyra in the background! Genius! Overall great little comic, incredible style of drawing, funny idea, and it all comes together like bread, butter and jelly! 9.5/10
