That's a very nice start, I agree that this image would be much better if you leave it in black & white as pure pencil work.
Shading on rocks is done very good, you can track how the lighting source go around those bends and curves, that's fine.
But, image has some issues.
The main one (and sadly u can't fix it anymore ;{ ) is the minor and mayor. If you have just put at least 1/3 of sky above the house everything would have work just fine. I know you wanted to focus on the waterfall and rocks, but this way observer is getting lost.
You start looking at the image from the center while it was possible to have focus point on the mill and then, down the waterfall. The whole piece would be more exciting.
That way you would be able to put maybe even contrast between dark sky and bright waterfall, to maybe put some meaning behind everything.
Second thing (which you still can fix) is the waterfall itself, to be precise: the water. It doesn't look like water at all, it looks like melted cheese. By the shadow it casting it's suggesting that it has great viscosity. But, you can fix it without any problems, using different strokes for water.
Also, don't forget the water condensation at the end of the waterfall, everything will have to be more brighter there. I guess you're planing to add some trees and stuff like that?
Anyway, it's a good start, now you just have to be smart with finishing.
