Mmmmmm i must say that this is a very interesting piece, I will start by saying that the abuse you have used in this picture of HDR has really made this picture a captivateing moment in time. But because of this there is some noise towards the ground and in some of the blackend areas, But this is normal if abuseing HDR. To fix it just take it in photoshop and cover with the same texture as layed on the actual picture, But to be honest i dont think this picture needs anything, For the way it stands is really a sight to see. One that has tingled my ever so dull mind, Well done in captureing this moment and being unique in the way you are not afraid to experament and get such a brilliantly composed picture!, You have a talent i look fowered to seeing more art of yours in the near future!
Thanks, I appreciate your kind words! The tiny white spots in the lower left corner are actually from the layer of ice on top of the snow, and not noise. Actually, I purposely applied a very subtle grain to this photo. I might like it without the grain though, I'll have to think about it.
