More drawings like this, keep working on the positioning. The anatomy on this one is just right, while the other drawings I've seen in your gallery tend to be a bit too extended on the jaw from the profile view.
The sizing of the head is good, the ears are a bit off in height from each other though, eyes are a tad bit off as well on the positioning vertically. Like the left eye is a tiiiiny bit higher. The nose... looks good, I think it's more of your styling being used here than anything, and that's fine. It might be a tiny bit high in my opinion, but you're the artist, your imagination ts all good. However the nostril, the fact that you shaded the inside of it, creates an odd illusion, like it's almost out of place. I'd say try not to focus so much on the illusion of the loop going under, and in. In this style of drawing, and definition, I'd say a more flat outlook on the nose fits. The overall soft tones work really well, specially with the cross hatching technique. You've got that down to the T. Keep going with it, try to use it in the right places though.
