Of the figures the Lion characters look the most cartoony. The Wolves look cool especially the one with the scars across his eye. The crocodile faction has some good castle Lizardmen possibilities. The eagles could be good for customising and the ravens look awesome.
The Raven and Eagle characters wear a helmet with the beak over the top of a traditional Lego head. From the blurry pics it seems that all of the characters are wearing armour or loin cloths, theres no high tech or robot printing which means it should be pretty easy to convert them into castle figs. The new wing pieces look great, I can picture winged knights
