Nothing is better than a dutty animation in my opinion.
I have a love for the colour schemes that Firth uses, they are often quite bland, which reflects the overall mood and atmospher of the characters and the story’s themes.
A lot of Firths cartoons push social taboos, another thing I like. For example, some of the animations are about mental illness, or drugs.
What I also love about Firth’s animations is his choice of music, such as Boards of Canada, Aphex Twin & Brian Eno.
The addition of music to animation can really set the mood, weather it be a more obvious use of music, or a piece of ambient music in the background.
