This turned out great, Mark! I’m so impressed that this is your first time sculpting a face to this degree. And a caricature no less. You chose wisely in terms of features to exaggerate. Your sculpt definitely resembles your friend.
While yes, there are some areas that can be refined/polished, you’ve accomplished a caricatured likeness quite well. Nice work – It’s an A in my book.
Sure, if you’re illustrating your own character, it’s fine to submit with next week’s homework. So long as you have time to both illustrate and sculpt 😅
