Work in progress

Ran a workshop today in which I shared a charcoal technique that I was taught in turn by an incredibly talented artist called Lesley Humphrey. The workshop was part of my exhibition and it was good to see people really taking to this method.
This is one I started although it isn't finished yet. I need to do something about the far fells, they aren't snowy or solid enough. The trees too, look lost and I'll-defined.
I also need to possibly add something in the foreground? Sheep maybe?
But still, it isn't finished ?
