The earth is pretty old, so makes sence that the earth elemental would be old too, here are 3 basic old bodies on which I will add mech and magic elements

and some sketches for the first body:

skethes with the second kind of body, next one will be fully retro, its kinda starting to not relate to nature any more, too many mech parts

So went into the medieval direction, apparently it fits more into the "elemental" fantasy that u would expect to see but it becomes a bit less striking more boring, also tested some colors.

for the future she should be naked, the more of her it's covered the less it says "earth elemental"

also using animals or animal forms for war could be a good idea since they are also of the earth (not vulture but wolves, bears, dinosaurs?)

naked with animals, removed lower jaw (bad move because it makes her less expressive).

third body type, with wooden armor and staff

Here is the last bit of exploration, settled on a more fantasy looking earth element, combining magic and metal armor, plus, the flag and decorative parts, also the armor is very decorative to express her status, as "champion of the earth elementals". also naked as mutch as posible because she would be made out of earth and stone and wood so theres no need for clothes other then defensive purposes (armor)

@mr_dessin thanks im happy u like them, the first image of the batch above is a bit too normal fantasy I think.. too little magic ? thats why im going with the last one.. magic sword and metamorph ability (she can make body parts a lot larger like her left arm)

so here are some face expressions, will finish the character from now on and start the final image

@Oceane_Roh Thanks, yes the mech is interesting but it doesnt say "earth elemental" to me.. reads like "old lady with robot parts"...

final character, will start the presentation image from now on

@mr_dessin thanks

4 versions for the final image, trying to show her atacking power.. probably will go with number 4 since it shows great power being able to cut a castle in half.. and mountains in the distance. The rulles say the character must be shown attacking.. doesn't say what to attack..
