My first map Kill the Lich King

this is my first completed map, and i cant host on my computer and would like the advice of people who are familiar with map making. I know it still probably has a long way to go with much tweaking invovled but this is basically waht it is. I have made a map in which the Lich King is finally reunited with Frostmourne and is able to "live" again. He plans to claim the life tree's powers for himself, but nobody will just take it lieing down. Sargeras angry at his betrayal has sent the burning legion to crush him and intiate his final invasion. The nerubians though small in number have resurfaced to reclaim their lands of Azjol-Nerub. And of course the humans have come to his icy throne to kill him and along with him the plague. So far there is no real special fightin about it, its just about building up and army and destrying your opponents. I havent added any special abilities yet or anything like that so i hope its not too plain.When you have good ideas or would like to comment on somthin pls dont insult me just give me good advice and tell me any bugs or problems there are thanks!
EDIT: i have now uploaded the map Enjoy!
