I'm not sure if it is helpful. My linework is sloppy. Anyways I got some practice out of it, which is something I need to do.
Edited to make the original linework easier to see. I pretty much kept the forehead and where the snout meets the head the same.
More less I made the snout shorter, made the head bigger. (there needs to be considerable space between the ear and the snout.) Nearly always I tend to shade in the top of the snout, which is something I do, not necessarily helpful for anything.
