I'm still exploring, but i may focus on fire element.
Here are some really rough sketches
i may continue with that concept 
Both #1 and #2 are pretty cool.
2 more, i think i will color 3-4 different ones and than decide which one i want to push.
Which concept would you guys continue with?
The first fire concept, because it's epic and it's the one who fit the contest theme the best, maybe with a bit more of movement like your previous iterations.
The earth concept looks promising too, the swampy/muddy atmosphere is more original than the casual rock. Perhaps you can mix stone bodies and lively ones, it's also easily mixable with your second fire concept.
All colors great. But - Fire! Definitely! 
Thanks for the input guys!
First one does fit the theme the best but its a bit generic in my opinion.
That's a really though decision, i detailed each one more but i still cant decide.
What would you guys take?
i kinda like 2 i think it could be a pretty cool piece
I also like 2. 3 is neat too. I just like things dark and creepy XD
2 and 3 are very intriguing and would give you alot more to play with in terms of character detail and story. The 1st concept looks really cool but it reminds me of Gears of War. Can't wait to see the final result!
My fav is 2. Can be more convincing & tactile, as I see it. GL!
Yea 2 & 3, 2 if you can make it something more, idk maybe the thing behind her more than just a pile of people? looks like that to me.
3, can be really cool looking, i like the mysterious shadow people/hands surrounding her. For me something is missing for both 2 & 3 idk what it is though.
Thanks everyone for your feedback!
thats still a really though decision
Definitly right, in terms of design and story 2&3 are better
I love the second one, the earth design, very different and has an ominous feeling to it. Like you said the first one is a bit generic, but what you did there with the red accent (blood i think) of the earth painting is very original, i think if you push it a bit further it could be something really awesome!
I like the third illustration. Cool idea with hands.
Absolutely love that first one, really intimidating! Great work so far
