The same principles apply to pretty much anything with limbs,wings, etc. An european-styled dragon would have a maybe 2-1 or 3-1 front-back split, depending on the wings and the tail.
The proportions of the division depend on whether the final fig would be top(the golem)/bottom(a centaur) heavy.
The only thing this fails me on are spiders. Getting the legs to be thin enough to look right, as well as strong enough to support the body .
I'll probably have time for another series sometime next week, so suggestions for the subject are very much welcome.

Also, i'd like to remind everyone that a new 'main' figurine gets started on friday 15th, so i'd like some suggestion for that by then .
