It's pretty good and the snowy/fuzzy effect works well here. If I have one gripe, it's that the low contrast and many levels of grey don't define the volumes or shadows very sharply. If you ever have to redraw a similar figure, I suggest applying strong shading first (for example 2 very different shades), experiment and fix until it looks good, and only then you can smoothe the transitions over many colors.
Yap, in the near future I will try to paint so. Thanks)
