I love dip pens! And this piece is amazing! Did you use a reference photo? Oops, I see a mistake, right above the head of the dear on the left, there's just a patch of white, but in the reflection in the water, there's a stick rising out of its ear. The complexity of it isn't very consistent, though, since the far bank is almost all white and featureless. I would suggest just a few dark lines to imply trees. (as you did with those faint trees just above and behind the deer on the right) Awesome work!
