Well, he's been into map-making for at least a year now, and this is his fourth map, but there's no progress to be seen. And the maps are posted in the RPG section, even though they have nothing to do with it; it's just a typical "kill all enemies" scenario. Not a single quest house is filled with anything.
Although, we can probably make allowances for the author's age.

Is age an excuse? o_O I don't think so. If a person is 10-14 years old, then they should already be getting a good kick in the pants, IMHO. Especially if the map is for the third or fourth game – there's absolutely no such complexity here as in G5-G6, where you can't figure out even the basics without a good understanding.
I'll take a look at the map and get back to you.

P.S. It's best to find a competent beta tester.
P.S. I made my first map for Heroes of Might and Magic 3 when I was 8 years old, and it turned out pretty well
