Yoo bro, first off sick work. It looks really clean, not much going on. But there are a few points that could get some improvement.
- The crab, its kinda just randomly sitting there. And it is fully symmetrical, just try and make it look a little bit more 'real'
- Island, islands are really great, not to big, no need for long searching times when you need loot. But might try and smooth it a little more. Like it's just a little like a cylinder right now.
Anyways, this build is not bad in any way. But there's always room for improvement.
