I really like this MOC. You picked a good stage of construction in which the form is easily identifiable, but there is still plenty of work to be done.
Also, you might consider adding some sort of device to catch the logs with next time (rope, pitchfork, a row of rocks placed in the water, etc). Have you ever tried reaching out into a river with your bare hands to haul out a log as it passes by? Sounds like a good way to get wet, I'd venture to bet!
Keep up the good work!
