Winter is a beautiful, and cruel, mistress. With Blizzards and subzero temperatures being something to feared, as the plants die, the animals migrate, and the people locked inside there's not much to do but wait. Marzanna makes the bitter cold season much worse than it seems, the longer the winter stays the more dangerous she becomes. Blizzards ravaging the land, killing livestock and people alike, and covering the area in thick ice and deep snow, Marzanna enjoys all the death and misfortune she causes with a wide fanged smile on her pale cold face. Until her time to go during the spring season, where she returns to the realm of death and her sister, Vesna, would take center stage and undo the damage Marzanna has caused on the moral world.
With the gods busy on the battlefield, they leave Marzanna unchecked and ready to unleash a never-ending age of winter.
In terms of concept art, which one do you think looks best?
I DO want to say one other thing though, and this would sort of apply to everyone in how I'd personally judge these concepts. The concept of the kit, and not the numbers you apply, are really the most important. We would rely on HR to balance the god's kit (somewhat) reasonably.
So in this case with you, I was using your numbers and the completeness (or lack) of the understanding of the kit, and being nitpicky because I've known you for so long. I won't judge too harshly on damage numbers for anyone, because those can always be changed. But when we talk about the "balance" concept in the contest rules, I think it's more about what the kit provides. If the god has 2 escapes, an overpowering ult and CC in every ability, that's unbalanced.
