I find this map a bit intresting. You have tried to almost replicate the original map, to a certain extent.
It is like a selective pathblood, but here you have to have resources to buy units and fight.
If you would have added Kill gives reources, rather than just tributing reources with timer
it would have been good.
Also the towers should have wall around them so they cannot be destroyed quickly. Also some extra attack to towers might do a good job.
Then increase wonders HP, and make it heal automatically.
You can find the trigger setting for it at the
Scenario Design FAQ, in the forum.
Then perhaps adding some wolves or traps on the road?(Just a suggestion)
Also increase the time required for the spawn of units, as the resource is consumed more than the given units.
