I thought at first that this might be missing the mid-values. But when I'd adjusted the paper to near-white, I was mistaken. There's a lot of good work in this. It could be refined in a few places, but that's nothing that experience won't fix - and fairly soon, I expect.
I do have a couple of suggestions that might help.
First, I'd engineer a shadow for the ear - even if there isn't one in the reference. It not only throws the ear forwards, it also defines the shape of the side of the face. You have to keep a really sharp edge on the ear for this to work. You can use that for any flop-eared breed.

The other refers just to this dog. We humans look for and recognise HUMAN emotions and facial signals in dogs. I'm quite certain the black patch under this dog's nose is part of the flew on the far side. BUT it looks like a pout. Or perhaps a partly open mouth. I think I would have pushed the flew back a bit and pulled the front lip forwards to hide most of the black interior. And then dulled any highlights in the flew, so it no longer attracted attention.
Finally, try to create a pinpoint of key highlight in the eye. Then expand it to either side as a reflection. Where the reflection (of the sky, usually) is
never as bright as the key highlight. That way, you create an intense highlight right next to the black pupil that's guaranteed to immediately attract the viewer's eye.
That said - I always appreciate your view.
