Looks nice, I will check this one and leave comment!
EDIT:
Well I played map a little bit and I must say that I am somehow disappointed in some way!
1st - Bullet is flying on ground not above!
2nd - Constantly clicking F and then target place/unit become boring fast, make spell instant! I click "F" missile is fired in hero facing directio!
3th - Monsters have range attack, (I pass red gate and get killed there

), make them zombies with small damage, fast and melee attack (you played left 4 dead?) (Maybe is there already something like this but in my opinion dwarf with shotgun is a little bad)
4th - Camera is very poor for this kind of game! Change angle of attack and make it face hero direction or whatever! You can even create custom one so player can zoom rotate etc etc!
5th - Terrain looks ok, but something is missing, maybe some more blood, corpses etc etc
6th - Add some special effects (unit killed with shotgun or rocket can explode, add blood bloooood bloooooooooood)
All else looks good, descriptions, sounds etc
I really like map, please improve some small errors and add more to map like tips, hints etc etc!
I will wait for update to rate this map
