dont stick to the grid when making roads, you only should do that in a city rpg really.
Grids can be fine in certain builds. It's not at all uncommon for cities to be built in grid systems, particularly in America (e.g: New York). But it is less common in England (bar Milton Keynes).
But on a small island like this one I would agree that it doesn't seem normal, but that's understandable since it is for a city rp.
Remove some of the trees, and recolor some of them similar colors, also PLEASE add more room for building lots, you don't need roads surrounding every single lot, wastes space.
This is good advice. There are too many roads, particularly when there isn't very far to go on this island. There should be sections of the town (especially near the beach) where it should be entirely pedestrianised.
Try making it sea-sidey, so you have slimmer streets and more buildings built in rows. As it is a cityrp, promote the idea of having bottom floors act as shops/cafes/restaurants, and upper floors be private residences. This saves you from setting up distinct residential and commercial areas.
It's also worth noting with your roads that they are particularly large for quite a small island. Don't be afraid to make them half the size, and have slightly more pavement.
You're on a small island so there isn't going to be hundreds of cars on the road at any one time, so don't be afraid to make 1-way streets.
Overall this means much more space for pedestrian movement and more space for lots. And remember that lots don't have to be seperate from each other. You can have rows of buildings of equal or even varying sizes all next to each other.
