apply that sam
The red writing at the start looks really messy and the times new roman font didn't seem appropriate - something big, blocky and sans-serif seems like it'd work better.
The clouds were drawn pretty well and other graphical highlights included the text on the list, the light streaming in (with particle effects), eyebrow raise, hawt sause, the sequence with the pot travelling through brightly coloured patterns, the start of the fish torture scene and the background during the ending sequence.
During the fish scene, the lips seemed to stop moving for a while.
At the end credits, text is way too bright to have enough contrast to read comfortably. Make it darker and perhaps more saturated. Maybe brown?
A lot of the time, the brush strokes seemed a bit messy. I'm gonna guess that where it was cleaner you just spent more time on it. If you carried the standard of the parts I mentioned throughout the movie, this could be an award winner! Do the work!
I couldn't really understand it all and though some parts were fun - fish/skull-bouncing/yellow smiley... - a bunch of sections just weren't fun to watch as I couldn't understand any of the lyrics nor the narrative. So where he was putting in things into the pot, it seemed more boring than suspenseful or whatever. If you wanted it to be more entertaining, maybe you could have had little jokes for each item. Once could be a handful of maggots - he'd open his fridge, find a mouldy sandwich with maggots in and pop it in.
That's just an idea off the top of my head. I'm sure you could do equally good or better ones for the other ingredients.
Anyways, all in all, I enjoyed some parts of this graphically, and the end bg is beautiful.
However, you need to work on your story-telling and apply that same graphical polish elsewhere.
