Cernunnos: it's just a Theseus model with the animal buck antlers. the animation of the buckattack is not badly, sin that when it hits another Cernunnos, the Cernunnos that receives the hit disappears, when it hits from near an enemy the horns are moved as if they were not attached, the textures are not detailed and are almost simply of a white color, besides the idea of the horns above the head, has been already used in the mod Age of Celts Bar Version by skystrider.
Celtic Fairies: it's just a Caladria model with new textures and a new rangedattack, the textures of the body are not detailed and are almost simply of a white color. nothing special.
Taranis: It is just a myrmidon model, with a dwarf head, with the textures that are almost simply of a white color, it is nothing special, then when it attack an unit it races next to the enemy and then it disappears, however then it never reappears, it is invisible, this is a big error.
Thunder Giant: it's just a Fire Giant model with the textures with a yellow color, the texture is not detailed, that texture can not be marked for creativity, it is only colored with the yellow color. when it hits with the rangedattack it launches some projectiles that change of form in strange way, this change of form of the projectiles is an error, because it changes in conformity with the type of unit that hits, for instance when Thunder Giant attack with the rangedattack a fortress, it launches some projectiles with the color white and yellow, with the square form, besides around the hands there are some big white spots with the square form. this is surely an error in the Ball of Zap.
All the units don't have the sounds and besides they don't have the icons.
I give a 3 because the buckattack of Cernunnos is original, but the whole mod would deserve a 2
