Not too shabby
So your efforts here are much more complex than the original (this review will refer to both parts of episode 2), and it certainly shows that you're trying new things. This is good.
There's 3 primary issues I have with these, though. The first is your pseudo yell. I know others have harped on it already, so in brief it's not convincing anyone that it's a yell. Problem #2 is that the sound was really rough here in part 2, and the difference in volume between the dark lord and other various characters resulted in my constantly adjusting my own volume. It was really not fun to keep changing the volume is characters alternatively screamed and whispered to each other. Last but not least, de-saturation can be good, but the saturation is half of what made the first episode and first half of episode 2 so much fun! The rich colors and vibrancy of it all- it was cartoony, but this gave life to an otherwise unbelievable and genuinely rotten character. It made the evil dark lord go from an a$$hole to a really fun fellow that just happens to want to kill everyone.
Take these as you will. I will probably watch more when and if they're made. The above are merely my thoughts on what worked and did not work.
All that said, you get an 8/10 and a 4/5.
