I think it's a good idea, but I can't make it good 
Oh it's not incredibly clear her hair is water, I just thought it was a shade of blue. If you want it to look like water though I would recommend looking up some ref and incorporating that more into the painting, adding more reflection and refraction, darker areas and a little bit of translucency so you see the skin through it
What do you think? 
i loooove these lil babas
But you have no idea how I looooooooooove them 
Ahh t h i c c
Those babies are great lol she looks so bothered by them all the time xD
Really love your stylized anatomy and expressions! It's such a unique sttyle! Can't wait to see what you come up with /,,/.
I think front side concept is done 
Beautiful! I just think that she needs a little bit more of light on her beautiful face... The babies look great too, I think they look best as friends!
Love the translucency in the hair and also your realy unique design🦾
Now hair is flowing 
Sorry I use clouds-placeholder 
That definitely looks a lot more like water, the colours are blindingly bright and I love them lol
What size must be a final illustration and concept shit. I don't found this info.
I don't think there is a size limit or anything this time. id ask the original post if you can. looking good. also some feedback. if she is a water element or is related to water. maybe introduce some water decoration/designs on her and the little guys. like starfish, shell pattern, scales or something to tie her to the water. the colors look great and the personality is there.
Lovely and funny(in positive meaning) work!
the final illustration has to be at least 2048px at one side, concept sheet isn't necessary this year so do as you like 
just to be safe 
Not sure if you remember about this rule but... We all have to depict our character(s) (either attacking or defending).
"This is WAR - Your champion should be depicted either attacking or defending!"
Seeing her pose, the easiest one could be a shield around them or something like that ?
But you certainly can found better, of course.
She reaches right hand to the weapon in the water to protect a children
I agree with dessin on that she doesn't look to be doing either, mostly just chillin in a pool with some laddies, but it's a bit late to change things around at this point, unless you could remedy it by lifting her arm up just a tad with the weapon, like holding it up in defense maybe
