(I don't know if this review is useless to you now and you've improved since then, but whatever)
Voice acting- The voice acting captures the script perfectly, and every character's voice fits in with what they were saying and how they look.
Script- The main joke of the video was funny and the jokes were funny. The pacing of the video is spot on.
Lip-Syncing- Not much to say, just that the lips on each character moved near perfect to what they were saying.
Color Palette- A lot of the colors in this video are all the darker version of colors (Mostly) Just look at the first glimpse of his computer. Try not to take each color to the extreme (Too light/dark) And get just the perfect mixture. If you wanna know what I mean by perfect mixture,I think you did it pretty well with the blonde character.
Animation- The animation got kind of weird at times (Except of course the lip-syncing) I think sometimes the characters move way too fast. Just look at when the main character bites the other character's ear off. I had to rewind to see what happened to his ear and why there was blood on the guys face. Also sometimes looked a bit chopy.
Drawing- The drawings for the most part looked extremely crummy and the lines are really broken. Just press Control+Z to undo and then draw the line again, it may be tedious, but it works. The characters ears/limbs/chin never seem to really fit with the rest of the body.
