Fantastic work for a first sculpture! I would not have guessed this was your first time. Excellent work 👍
The boards look great. I love the slight orientation differences – that kind of imperfection effort is gold. My only real note is that the border frame of the crate is one solid piece rather than multiple pieces:

As if it was carved out of one massive log ha. Simply add come butt-joint crevices with the crease brush (pinch and scrape for refinement) and you will solve it.
Oh and consistent grain detail on all boards (the bottom of the screenshot is lacking). This may be a WIP and you already know that. Extra time taken for sculpting is OK btw. Week 4 is a buffer week for everyone to finish.
