Hi Kam, I played the first versions last year, I dont like it much, but I played these lastversions: the map really became great! Thats the best wc2 to wc3 conversion I ever played. Congrats.
and I have some suggestions:
1) What about giving Knights the Cleaving Attack ability instead Footmans? So, the Footies wold act as a defensive unit (you can make a research called Mistic Armor that would increase footies armor by 4, or just give Taunt ability). In that way, Footmans would act as defensive units, and archers and knights as ofensive ones.
2) Dont you think the starting current food to much? You should make it smaller, so people would have to build more farms.
3) The only thing I disliked the map is the heroes. First, shouldnt I able to choose them? Why when I start playing, I have a pre-placed hero? (PS: I already checked if, the option to start melee maps with pre-placed heroes is off. It was off, but it still started with pre-placed heroes.) Second, looks like you have made some fusion betwen the wc3 and wc2 heroes, like, I started with an archer hero called Sylvanas. Shouldnt it be the legendary Alleria? Also, you need to give the heroes some spells.

Zul'Jin - The Hive Workshop - A Warcraft III Modding Site
If you decide to add Zul'Jin, use this model, it does kick ass =D
There were also a Wc2 Orc Barracks by Red XVII, but I cant find.

And this for Rangers
Otherwise, great map! 5/5
EDIT: PS: About a snow map, I can make the terrain for you, if you want.
