Thank you. 
Its hard to stop myself from complicated decisions:) but I will try to simplify some things
I don't know why but the second image is calling me ^^ (the one with red sky)
But probably because of the fun Green / red contrast.
That is a very cool idea having three fighters in one "person". You've done some nice, dynamic poses for your champion. I suppose these colored sketches are compositions for the illustration? Looking good! c:
Yes, I'm looking for a color solution for the illustration.
Thank you.
I like the middle one's background and the green fire from the last one.
nice work so far
It could work if you put a mirror or some type of reflective surface somewhere in the final composition that would show any of the characters that get hidden.
I like how you solving the composition and character design. I like most the composition you choose at the end. It's pretty dynamic and every character supports each other, good job. Only one suggestion, I have the feeling the character need more space to breath at the top. With the less space you stop the dynamic momentum of the swinging speer.
Thank you. Now i feel it too)
i like the mid one, the oranges palette works really nice with the pale violets, the green variants are too much aggressive imho, personally i would try to implement the bkg to add a lighting element, if the cauldron is your main light you have to figure out better the shadows it will cast, but if its your secondary (if it is like a fire or a lamp the decay of the rays can make it more like a glow) you can have maybe a direct ray to shape your character the way you feel better
Thank you. I also like combination of color in violet variant and its in general look interesting for me but in green one beter focus on character comper to violet. I cant say that i 100% with green variant, so it can change on the way to final. Cauldron fire is secondary light.
The green and violet go great together, great choice!
