I gotta say, I didn't hate it. The concept behind it was pretty good, and the jokes had some good timing. Only gripes are their heads being a little too mishapen(the hair is no excuse), and I half wish you would have cleaned up the backgrounds a bit more, or at least blend the sketchiness in a bit better.
As for the voice work, DruoxtheShredder definitely was the stronger voice and had a lot of character. As for you good sir, you definitely had some strong points and were giving some good emotion in parts, but in some instances you pulled back, and it felt like it broke the character a bit.
All in all, a good short that shows the talent of the artist and the voices behind them. Keep up the good work, gentlemen.
