An overall really awesome comic strip. Humorous, original and well drawn and coloured. Vision wise, I thought it was clever having Trixie wanting to be a part of the main crew and would go to such lengths as to perform mundane tasks for the current main six, something that I think could actually happen if it were to be in an episode. Though I can't give it 5 stars as the whole idea of Trixie trying really hard to become friends with one or more of the main cast or secretly loving them has been done quite a bit before.
For originality, I thought it was quite unique. I'm yet to see another comic or image that shows this kind of scenario, nor anything that resembles it too much. No real gripes here.
For your technique, the art style is wonderful. Really vibrant, very stylised and unique, exciting and fun to look at. Though I had to take a star off for one fairly big reason: your speech bubble placement. Reading through the comic was fairly confusing, as the speech bubbles were placed all over the comic. It should read from right to left, top to bottom. In this case, Trixie's text should be placed above Rainbow Dash's and to the left, with Rainbow's the the lower right of hers. Pinkie's speech should be above Applejack's, as should Spike's, as it makes no sense reading it otherwise. It took my quite a bit to figure out what was being said. For that, you get a 4/5 for Technique.
Overall, the comic is very well done, despite a few minor flaws, and the humorous story paired with the vibrant art style gives the comic a big impact on readers. Overall, very well done.
