This is really good, I don’t think I have any pointers or any feedback I can give to make this WIP any better ATM!
The only thing I suggest (and I read the replies) is replace the other grass with ROBLOX grass, I do understand that you want to edit it the way you please, but it might help with performance or part/tris count in the end over using a plugin : )
Lastly, it would be the lighting, perhaps changing it to a more “hey I’m in the middle of the ocean, and the sun is literally beaming on me” ambient might fit the scene better!
Looking great so far! Maybe you should plan out and follow a certain color scheme, as well as experiment with lighting/camera effects to harmonize and give the place something extra. GLHF!
Great work, love the barrels especially though, keep it up!
Maybe add a sort of dock / fishing area on the island to give it more of a realistic feel to it, and some extra detail and build to the island, and maybe build like a sort of pirate ship off in the distance in the ocean to give it more of a pirate theme.
