Aye the blue/gold/red is a combination more associated with royalty, whereas the first one looks more like a nature landscape. Well thought out and looking fun.
Thank u) I like the second option too . The colors look like knight armor (metal, gold). I want to make reference to the medieval battle.
I do two stages in parallel. Developing a character. Play with the perspective)
Man, I love this rough in from 12/5/18. Totally digging it.
Are you going to mirror the shapes and color language on the horse? Kinda techono armor horse engine kinda thingey?
I think to make a horse mechanical. This is not a robot but the elements of the body are mechanized. The same with the war. 
Color and details 
The idea is very cool ;3
Good luck!
pps:
Мне так понравился стиль, что я аж на артстейшен подписалась. Оочень красиво :3 удаченьки
Хи, спасибоооо ) буду стараться
I started with the line, added tone and color. Now I do the detailing. I also realized that I wanted to make the whole horse a robot. I want to add some interesting object to the foreground of the picture, but I have not yet thought of what it could be (bushes, fog or something else)
Both versions are cool, but the new one does feel more striking, good luck with it!
What is her superpower? (I think it had to do something with boosting morale before? Curious how you'll show it :D)
I think about the character in the illustration process. It'll be more understandable in the concept(about to her superpowers). Morrigan is the goddess of war in Irish mythology (I like to be inspired by myths.) The goddess herself did not take part in the battles, but she certainly attended the battlefield and used all her power to help one side or the other.
In the illustration, a girl riding her horse. here she is not at war, she will have the next fight, and she should choose the right side. honestly, I don’t know how to show morale. -_-, maybe if I will have time, I'll think about this moment. 
I'm not sure how to explain properly what I have in my head, but maybe have her surrounded by a group of warrior that look hurt and damaged, as if they were in the middle of a tough fight, but they're all getting up with a determined look, with their weapons ready to attack. I don't know if that makes sense, but that could be a way to do it.
I dig the way you explore color. So much vibrancy
Yes, your question made me think. I thought how to convey the atmosphere of the battle and I I did it.
