I watched him build it, he did not go off anyones design so dont try and take his credit away, idk if you have similar lighthouse but dont just jump to conclusion that he copied off of your design, the lighthouse is pretty good btw, the top could be redone a little though in my opinion but the basic design is great
Edit: just looked at your lighthouse pyro and his is much different from yours, first of all his is larger, has less stripes wrapping around sides, the top is dramatically different, and his gets thinner as it goes up, yours does not change in width whatsoever. Don't be so quick to judge someone else's work. both lighthouses are good in their own way
