I did several tests for this concept, I wanted to make a cold scene, with snow and a lot of wind, I also wanted to add an story, that there was a structure that hid something dangerous and someone that could to face it.
Lately I try to work the forms in an abstract way and without many details. I think the first image is good (I think the light and scattered red dots give it more drama), but I post the previous ones, which do you think it's more interesting? What do you suggest? if it gives you a little cool it's fine to me.
