Hooraw! I did it! It is finally finished, I hope you all like it, It's not as good as Sir_Blaze's Lookout, but I did my best. :D I only built the lookout, there is no bridge or adventure bay, you guys could attempt on building it but the other island accross from the lookout isnt big enough. Anyways, Enjoy!
NOTE: after clicking the file, scroll down to the button that says "Minecraft World Save." Click that and you will be directed to download the file. Then open the file and drag the folder to your Minecraft saves. Enjoy!
