Let me first just say, welcome to cubebrush traveler, I do hope you find what you're looking for here! I'm insanely obsessed with the Medieval/Older time periods and I'd like take say so far amazing job furthermore, I do believe I can help with this quest of yours so let's proceed shall we?
Environment & Character Concept
- Now there's been something itching at the back of my head the moment I saw this piece and I couldn't quite put my finger on it till now. To me she looks like a Scandinavian warrior of some sort, I say this because of her equipment and facial & hair characteristics. Which comes to make me think.... Isn't she dressed a little to heavily for that desert like surrounding? I see there's a storm brewing however she just looks out of place.
(I honestly believe if your environment were to be changed to a tundra or a snowy landscape that this piece would work so much better. There'd be much more contrast between the carbon black horse and the Ivory white snow.)
I have a lot more I'd like to say however, as always I'm short on time... though I will return!
- (sorry for not doing an OP I'm still working my way into the digital world and honestly I'm unable to right now as I lack the skill set digitally/ that and I'm at school right now)
