No worries on being “behind” – Several people have needed more time to catch up. In fact week 4 is intentionally a buffer week for everyone to catch up 👌
You’ve made solid progress with you sculpted wooden accents! Some advice I want to offer is tightening and lengthening your grain crevices as well as adding a few more to balance the look. I would also subdivide higher 1 or 2 levels to avoid the polygonal artifacts showing up in the sculpt.
