Nice vocals
Heh, I remember watching you say you were going to do a better recording and I think you did a good job on this too. Also I am willing to agree those are two incredibly awesome show. Not the best in my opinion but they come extremely close because of random Pinkie and Freakazoid are. Kind of wish they would bring the Freakazoid show as well.
As for vocals, they sound awesome but I would probably increase the vocals by one decibel is all. Aside from that you did a good job on this, sounds a lot better with just one voice rather than two to four voices. Staring at the comic helps a bit but I kind of have my own vision of it with her just jumping around and doing random things while wearing a pony version of the freakazoid outfit.
Overall, pretty cool attempt, a lot better than the others anyways.
