The overuse of Topaz has led to some noticeable noise issues in the sky. In the future, to avoid this, selectively apply your filter by masking off the sky. Alternately, you can apply noise reduction to the sky prior to applying Topaz and that should help things out as well.
This hurts my eyes. The manufactured 'dreamy' effect is completely misplaced in this challenge. The image stopped looking like a photograph and is now looking as a digital illustration or drawing. Im sure this type of processing has its place but for me, here, it is completely misplaced.
With this style, and the high contrast between the dense branches and snow, make the photo hard to focus on. The growth almost looks like noise at this size. I am sure this photo looks great in full size, but scaled for DPC it loses a lot of the qualities I would have liked about it.
