Interesting MOC!
The tree is crafty and the spears in the water look good a serve the purpose well, but out of all three that are floating I would imagine that at least one would have an arrow head heavy enough to sink. A 1x4 rod sitting out of the water would have looked nice there as well. The photography is okay, but in the winter seasons we can never expect the best sun-based photography.
This MOC still has a great design and is an excellent entry into CCC.
