This is lacking, I'm sad to say. I kind of like the idea and see where you're coming from (I too considered something like this, only doing it differently, as we are all individuals), but the way you presented this idea is almost completely pointless.
Let's look at what you actually did so you may see where I am coming from. You only really changed the models of the units along with their names and respective tooltips. You didn't change the units stats or anything. You even said on the Hawk Scout tooltip that it can mount a Wyvern, an interesting feature that was no where to be seen (there wasn't even a riderless Wyvern). Although the idea isn't all that original, it would have been nice to see that promise complete.
Then there's the greatest problem of all: no real for-thought. There's icons repeated, there's green icons (namely when I try to learn Command Aura for the Orc Commander, though I think I saw others), no changes to the Hero abilities... the list goes on.
Here's a list of the things that I disliked about each race:
Humans: I thought you said no Elves or Dwarves. Yet, no matter how much I rub my eyes and seek out help for so called 'delusions', I still see the Spellbreaker, Siege Engine and High Elven Archer. Care to explain? As if to make matters worse, you have a Longbowman later. Could that not have been the replacement for the Rifleman rather than something you were trying to get rid of in the first place? Also, Footman icon is repeated... *sigh*
Orcs: Mainly model changes... I acknowledge you added the Kodo Tower, not a bad attempt, but at least give it a different icon to the Kodo Beast. You tend to repeat icons a LOT, like with the Warlock and the Champion. Also, how does an Orc Champion get recruited at a Tauren Totem? I thought the Tauren weren't in this map, yet they still have a building.
Undead: Creeps do not count as new units. Also, there is bound to be some level of imbalance when it comes to using creeps. Additionally, this race really marks a lack of imagination. You use a Pyramid Head model for your own custom map and call it Pyramid Head... Also, you used the Acolyte icon 3 times, one time completely unnecessarily! The Wraith model has a respective icon! Where is it? Not here! Attempt at custom spell: Rain of... Annoyance, did you say? Need I say more when this is a custom spell?
Night Elves: Only one new unit, all the rest the same... and while lacking the expansion units! Instead of improving the race, you got rid of one of its units! Poor!
So, in retrospect, how much did you actually do? You say there are lots of new units, which I detest purely because it's not true (there are, at most, 4 new units out of all the races). You say the races are complete, while there are soo many factors you never changed, like the tooltips of buildings, repeating icons and just ultimately lacking originality altogether.
I give my reccomendation to those out there not to get this map, as there are no real changes to anything at all.
