There are a lot of issues with this map and is severely lacking effort in design and the description here on Hive. I vote for this to be set to Awaiting Update as it shouldn't have left the drawing board at this stage.
In-game:
1. The starting message begins with "Tower Defense Template." It seems you have taken a TD template and have changed barely anything in the terrain and even the triggers.
2. The builder unit uses standard foot movement and not flying. This means that the player cannot go form Point A to Point B without having to walk around the maze. Also, the lower terrain is inaccessible as there are no ramps to go down there.
3. The map uses standard Warcraft 3 units with no customization at all. Just literally adding default units to the mob pool.
4. There is only one tower, and it's also a barely customized Guard Tower that cannot kill any of the units effectively as they still have their original stats.
5. There's no point of saving your gold for the next wave as every wave sets the player's gold to a constant 1000.
6. There are a lot of gaps in the terrain as seen in the screenshots, and barely no effort to decorate has been made at all, except for the rocks on the cliffs that only serve to obstruct building towers there.
7. There are no info in the Quests tab, no multiboard, no scoreboard, and you don't even know how many lives you have until a mob reaches the end.
8. There are no extra game modes, other than the default.
9. There are only 5 waves, too short for any TD.
10. The map is still "Nondescript" in the custom games menu.
Hive:
1. You need to have a proper description that tells any potential downloader about what the map is all about. Though considering the amount of stuff it has currently, I think it can't be helped if the description is lacking.
2. Not really a major issue, but surely there are better titles than "My Tower Defense"?
I am not sure which of the stuff in the map is something the author even made, or something that already came with the TD template.
This map, at its state, does not match the quality of approved maps in the Hive, and a lot of work should be added before considering to upload it here.
I hope you work on this based on the points I gave you, and wish you good luck! Happy Mapping!
