well boy that honestly wasn't funny... i'm not even sure i can comment with "it was well made", but if it was, i think i'd have to rate it even less for trying so hard to go in the wrong direction.
what i can say is that at its core, you have a character that inhabits the word "derp". one that nobody but little kids and my little pony fans use with any bit of sincerity. not to mention a character that is simply mistakenly doing things isn't exactly interesting or new in any way. the entire use of an escape convict was pretty empty and irrelevant, though i guess it was used as a "plot device" to clumsily introduce the clumsy character.
as for what it did ok: the animation was decent. there was a written joke. the delivery was decent, and not very contrived.
thats about it. you really need to work on writing a more interesting character in a more interesting situation. i mean, i think the animation is perfectly suited for a silly webshow (since its not aiming for avant garde or any sort of visual masterpiece status), and you could definitely work out some interesting jokes. i just do not find anything interesting about a character that is literally a re-skin of "derpy hooves" or whatever the horse is called.
in fact the more i write, the more its blatantly obvious to me that the one major problem is simply the character decision. why did you make it about this character at all? its simply an empty character with nothing going for him but the size and the clumsy nature, and even that isn't very interesting since we have seen this kind of character before.
