Its nice! But you could add some fire place or lights inside the house, as it is too dark inside and add ancient things inside the house it would look good with your house design in game.
It looks like a very nice first island! Iād suggest adding a small raft to hint at someone living there, or else how did he get there? Also you might want to add a table near the chair outside, for a drink or something similar. Keep on learning and I hope you are enjoying Roblox Studio!
Add some irregular shaped objects like in real world.Add ancient objects like the things they use in ancient times, for example chair made for rocks.Add huge rocks outside and make the sand any random shape rather than a block, looks better now.Add lighting effects in Roblox Studio and then your island looks far better! c:
