The team from Canada, they "painted" their cake with brushes.

How did they do that? Watered down gel color or something else?

Thank you

Probably luster/petal dust colors mixed with a clear alcohol like vodka, gin or lemon extract. Or you can simply dilute airbrush color with vodka, which is what I do. But I believe you can do the same thing with gel colors for a more watercolor look.

They used the luster dust colors and vodka (or some other alcohol). They didn't use gel colors for painting. I thought Bronwen shoulda' won!

I agree j-pal... Bronwen's cake was best by far!
