That's a nice CD3 map! Have some rep.

Some criticism:
- You seem to have some weird clipping issue in the middle of the stone square (like you have drawn several stone textures on top of each other).
- You might want to give the labels a small, white glow.
- Not too fond of the texture for the docks. To me it looks a bit messy.

Otherwise very good, really! Nice layout, good use of textures.
