I was having hard time shading
I think the angle was throwing you off a bit. You could see to much of the underside of the tip of the nose with the nostrils which makes shading the bridge more difficult. I put red line on the lip and nose to show how the triangles would line up for the perspective.
Noses are one of the hardest things to get right. I had a teacher that told me noses have no lines and there is only value/shading to pronounce the shape along with highlights. This helped me understand the structure of the nose and how to look at it differently.
I don't know if any of this helps but I think you did a great job. Keep on Keepin on my friend.
