Seems to me like this map has a lot of good and bad aspects to it
Firstly, I highly suggest getting rid of some of the water, by adding in some new islands, or extending the main one. I guess you could even add a ship. This is the most prominent reason as to why I dislike Breeze Island. I get so sick of people jumping into the water as soon as you try to attack them. So annoying. So thats my first suggestion.
Secondly, vines. Vines actually create quite a bit of lag. Thats why SG2 is so laggy. It's not actually the buildings, its the huge amount of vines. So if you can, try to cut down on the vines.
If you can, try to add a little more detail to the map. Thats not to say it isnt really detailed at the moment, but it could use a tad bit more. For example, from looking at the pictures I notice a lot of bare roofs, when the walls are completely vine covered. Looks a bit weird. Add some dangling leaves from the roof maybe? And possibly some cracks. Try to add in some more mossy/cracked variants of blocks, to give it a little more detail, also
Anyway, good job
. If you get rid of a lot more of the water, you've got my vote;D
Edit: I freaking love the name also
