Hey,
Just gonna tell you about the things you should add on this thread and then I'll comment about the map:
1) You should add a poll, if it's possible with the standard format (Should this map be added? Yes/No). This one is to know people's opinion. <==
Just as @Savvy suggested.
2) You should add more pictures of the map to the thread because you've only added one which actually cannot be appreciated very well.
3) Add a description into your thread, this one is required always that you submit a map.
4) The map file download isn't actually necessary right now. You'll be requested by the staff management in charge of this when the moment come.
You can read all this at:

Now it's map time:
1) The map doesn't seem like a solo skywars map, I mean, the islands are built just at one side, leaving empty the other side. You should fix this if you want that this actually become as a map submission.
2) I can't actually give my opinion about the islands because the screenshots are took from so far away, anyways I'll give my feedback as far I can; Seem really basic islands and a small ones without space for pvp. <==
Again, suggest you take again new screenshots.
3) The middle actually looks pretty good, but we already have a skywars map with that same middle (or really similar) which is an inconvenience for your submission (the map is Ancient).
