Considering buying AoS. Please help :)

Hello!

I've played an intro gaming of AoS last week and I'm considering buying an army. For years I've been very competitive player in other games, and I'm looking for best possible army list I manage to build. In my LGS we are playing right now only 1000pts games and I would like right now an army list for that amount of points with a possibility to expand it later for 1500 and 2000. I'm liking the models of Wanderes a lot, but i think that Sylvaneth are also really cool, same as Icewind Assault. Reading through rules I came up with something like this. Do you think it is good, and can it expand well on more points?

Allegiance: Order

Leaders
Celestial Hurricanum With Celestial Battlemage (320)
Celestial Hurricanum With Celestial Battlemage (320)

Battleline
20 x Glade Guard (240)
10 x Glade Guard (120)

Units

Total: 1000/1000
