gonna be honest, I was half expecting the "AHMAGADSILVERSPOON" DT voice. XP I had honestly forgotten what DT actually sounded like, and was about to check but then i heard you do it. didn't really have to check after that. XP
All in all, good job. It's definitely difficult to do any one voice very well if you're not the original voice actor/actress. but you did these ALL really good.
Particularly liked Scoots and Applebloom. ESPECIALLY AB. At the risk of rambling on and on about my thoughts, I'll just keep it short and simple (cuz, believe me. i could go for hours on this subject.) You did AB's voice really well in terms of pitching and accent. It sounded like HER accent, rather than just a generic Southern one. However, you also did something that REALLY impressed me. You got her inflections really well, too. Each character in the show (well, every character EVER, really) has a certain way of speaking, outside their pitch/accent/vocabulary. A certain cadence, if you will. You got AB's down REALLY well. Not that you didn't do well for the others, just that AB has the accent, as well as the voice you'd have to deal with on top, so its just the most striking example for me.
Gonna stop rambling now.
