The assets for this are quite detailed, so it's nice to look at. The buoyancy makes for good immersion. However, I think the animation could've been a bit better. There was a lot of foot sliding when the character was running around and sometimes the camera shakes were excessive, which impacted the immersion negatively.
From a fishing mechanics point of view this was pretty interesting, making it a bit more challenging than many of the other submissions.
One thing that strikes me as odd with this submission is that it's a 3.4 GiB download, which seems a bit excessive even if the models are fairly high-fidelity. I suspect this includes pretty much everything you have in the project and you could shave a lot off of this by properly configuring how this is packaged.
