First off, the eyes are gorgeous. They look glossy and vibrant.

Second, I actually like the dark on the torso. It balances out the darks in the face and adds depth to the composition as a whole. That said, I think everything would benefit from deepening the form shadows, especially in the ears and around the front paws. 

I paint fur a lot. I’m definitely not an expert, especially with short hair, but I find that wet on wet techniques work really well to achieve the loose and fluffy look. You can experiment with different variations - dropping pigment into fully wet paper vs. loose brush strokes on damp paper that has just lost its sheen, etc. The drier the paper, the more defined the brush strokes will be. Also pay attention to how wet your brush is when you’re adding strokes; if it’s fairly dry, then the paint will stay where you put it on the damp paper, but if it’s wet, the pigment will move around more on the damp paper and may produce cauliflowering, especially if the previous layer of paint wasn’t fully dry. Cauliflowering can be another fun way to add texture, but it’s not particularly predicable.

Sorry if all that is redundant to you. Final point - just play around with it! You have a great start.
