Hey looking good! with the sharp creases and plane changes (like the wing of the nostril transitioning to the front plane of the face as you mentioned) observing the reference closely is really helpful. A lot of the time these "sharp" transitions are actually softer than we realize and making them overly sharp can make it feel unnatural. Usually it's better to have a transition between forms that's too soft rather than too sharp. these transitions also vary greatly as they travel so the crease is usually much sharper at the bottom of the nose and then softens a lot as it moves up and curls around the nostril. Hopefully this makes sense. Keep up the great work!

Nicely done! I like that I can see the forms of the nose but that the transitions between the forms don't feel too abrupt. Keep up the great work!

Way to do the assignment! One thing you might try to work on is differentiating the forms of the nose a bit more. for example the back of the wings of the nostrils there is typically a sharper inside corner than what I'm seeing here. Keep up the great work and I look forward to seeing more!

Nicely done! this is exactly what I like to see when it comes to these facial feature studies. Keep it up.

Hey great job! I also like to add the other surrounding features often so thats great! I can really see the likeness developing! Keep it up Scott!
