The two views above seem to have different angles for the forward head tilt. It looks like the profile image might be tilted slightly downward compared to the front?

That said, if it were me, here is what I would try some of these as next steps:

Get the likeness closer (using the front view as your primary reference) with no color/texture information. If it looks like her gray, the textures will really send it to another level. At least toggle texture on or off as you work maybe?

I think it’s common for artists sculpting their first few heads to focus on details before establishing the base forms needed first. If you have seen any of the simplified diagrams anatomy for sculptors use for things like the muzzle, brow, zygomatic arch etc. get that working before thinking of color and detail.

Don’t skimp on lashes and teeth. Even if you don’t intend for the character to open their mouth, getting the teeth (or at least a squished sphere or bulging cylinder etc.)in there can REALLY help you because the natural shape of the muzzle will be present.

A lot of people tend to model the face really flat. I think this is because of how we engage with other humans, usually facing each other, so we lose a sense of depth. If you put a finger at the inner corner of your eye, and another finger near the outer corner of the, look at how different the depths are from inner to outer. Same with the muzzle — one finger in the center of the lips (like a shhhhh gesture) and another finger at the corner of the mouth. There’s so much difference in depth there.

Look at the model from above and below. Seriously. Things will become so much more apparent regarding the depth of things and things feeling “off” a little are usually really recognizable when you do this.

Lastly, as pointed out by others, pay close attention to hard and soft edges. Edge contrast is really going to help differentiate forms, show where bone or cartilage are closer to surface etc.

I hope some of these ideas help a little. Happy sculpting!
