This reminds me of the feral child they found in the snow. When they tried to civilize him, he tore all his clothes off and ran into the cold snow and enjoyed it.... Very pretty and the watercolor is amazing!
When we think of a Lady of Winter, we use to imagine a young lady covered in heavy, furry clothes. I really like your different interpretation of her, instead: I like her being deminaked, and the boy next to her being totally naked: a naked body makes me think about shivers and cold...a perfect interpretation of Lady Winter! Also, the landscape behind them is really beautiful, and it also suggests this feeling of extreme cold and frost weather. Congratulations on the DD!
Nice. So original, both the character and the concept. However, I think that you should clarify the origin or the story behind your characters, so that viewers can get a good 'suggestion' to admire your artwork even more. Also there's a lack of shade (just little). Still amazing, anyway.
