This is my assignment of the ear from side and back.

It took a long time to give as much volume to the areas around the lips to avoid flatness. I had problems with the corner of the mouth. Redid them a few times. It looks like a smile from the side, but normal from the front. I can't figure it out. How can I do it better? Also are there any big mistakes?

First time refining something so much. I like how much it improved the sculpture. Do I have any big mistakes?

This assignment went better than yesterday. The improvement is visible. I will probably have to practice everything a lot of times until it gets easier.

The transition from the nostrils to the nose was hard to figure out when the model had a slow transition between them.

I think it went better this time. The bigger scale and the previous tries made it slightly easier. I'm struggling with the area around the eye the most and the planes of the forehead. Any tips for it? Are the mistakes still flagrant?

I have done and redone this several times. I either had the cheeks/forehead look flat or the eye look flat. Whenever I added material to one, the other one looked way too flat. This is the best attempt in a lot of hours. I have huge problems around the eye and making the eye look 3d. I think I can't judge depth well enough. Any tips to help with that? Where am I making big mistakes?

I struggled with symmetry a lot. There was a lot of "left isn't equal to the right", going back and forth between different angles to see my mistakes. I thought it would be step by step adding until it was done, but as I noticed from your video, I takes a lot of constant checking. How did I do? Any big mistakes I should have noticed? Is the mouth big enough?

Moved the chin over the mouth when finishing because it looked like I sculpted the mouth way down. Any mistakes besides that?

I thought it took ages, but it was only a few hours. Are there any notable mistakes that I should adress?

How do these look? I'm having issues with the frontview, especially in Loomis and Bodem. What am I doing wrong?

Slowly getting better. I managed to get a contour perfectly. I'm also getting adjusted to the size of things and spacial awareness. I realised at the end that that I have to make everything flat, not try to give a 3dish effect.

I really struggled with this one. I couldn't get it looking close

I deleted the 3rd one by accident. What are you opinion on these?
