I think I have a good method to it, and I might be doing some form of a tutorial for it.
I also like how every
I draw has different proportions, which is kind of nice.
Here are the things I have deduced make a cute
1) cartoonish eyes
2) curved, slim front flippers, curved, fat rear flippers
3) large amounts of chubbiness applied to underside
4) tusks that are curved outward and are right below the eyes.
5) no rear right flipper, it always ends up looking phallic.
6) 4:5 ratio of width:height
