outline is good,keep going.

Thats really cool 👏🏻☺️

I did not see that left eye correction, or else this looks first class to me. looks like there’s not much erasing, the Hair is the Killer. Good Job.

David, this is a great base to start shading on 👍😊
Your proportions and placement look solid overall, especially the eyes and glasses, they are sitting well and giving a good likeness already. The beard structure is also nicely mapped out. As Tehami pointed out, the left eye proportion is slightly off, so just take a moment to recheck the alignment and size before moving into shading. Small adjustments here will make a big difference later.
Before going further, soften some of the sketch lines, especially in the hair, and simplify the shapes a bit so shading becomes cleaner. Also double check symmetry while it’s still easy to fix. Once you start shading, build your values slowly and focus on big shapes first instead of small details.
You’re on the right track, this will turn out really strong 👍🎨

Nice work
