Demon Race, input requested

This is a repost with updates, i dont think i mentioned i wanted input and suggestions :)

Ok, I've been hammering out the demon race for my campaign, it's designed to be player controlled, so it's gotta be fairly smooth...here's the progress:

Units:

Blood Lord Hero: As pit lord, but with Flame Strike, Howl of Terror, Cleaving Strike, and Reincarnation.
Status: Need to get the Overlord a hero aura....

Mal'Ganis Hero: Dreadlord, with a Hero-type Raise Dead instead of Carrion Swarm.
Status: Raise Dead needs tinkering, but works just fine.

Eredar (warlock/diabolist/needs sub-name): Spellcaster, with Parasite, Dispel magic, and Bloodlust.
Status: minor stat tinkering, sub-name needed. otherwise done

Succubus: Spellcaster....thats about it
Status: Need to design her completely, basicly.

Infernal Machine: Siege engine, can learn either Liquid Flame or that burning ground demolisher thing
Status: Need to figure out final ability breakdown, may get new name

Faceless One: Advanced melee unit. Status: stat retooling, whatnot

Draeni Slave: Basic pesant unit. builds structures.
status: done, really...add in new buildings as needed.

Fel Stalker: Basic melee unit, can get Ravager Upgrade which makes them into Fel Ravagers with Devour Magic.
Status: both forms need stat retooling.

Voidwalker: Basic ranged unit. Can cross water.
status: doing fairly well, stats, etc of course

Buildings:

Forgotten Spawn: Since this has a birth animation, it gets to be a building...this is a much smaller Forgotten one (the one in the campaign was like 2x the scale of the 'normal' one), it contains the weapon/armor upgrades, because it's a keeper of lore and stuff. Is a Town Hall for purposes of TP scroll.
Status: building's fine, upgrade may need tinkering.

Summoning Pit: Uses Spawning Pit model, contains the Basic units (Faceless Ones, etc) and their special upgrades.
Status: Done insofar as Faceless Ones.

Temple of the Defiled: Temple of the Damned, with alternate name, it produces the Eredar and Succubus units, and contains their upgrades. Requires Summoning Pit and Forgotten Spawn.
Status: well, I need to finish the succubus.

Skull Forge: Basicly the Spirit Tower, it provides food, and attacks with fireballs. uses the 'Skull of Gul'Dan Shrine' model.
Status: slight tinkering, otherwise done

Altar of Darkness: Same as the undead altar, ya know.
Status: it really NEED any work?

Portal: Uses the summoning portal art from campaign cinimatics. produces higher level units. Requires Temple and Altar.
Status: barely begun. I need to figure out the higher units, and rename it...but the creating works fine.

???: I need some building for the Infernal machines...and possibly some other 'demonic mechanical' unit, perhaps the Obsidian Statue.

???: I need a building for the Laborers to return gold and wood to. it MUST have a build animation of some sort, and be something that could do well with 'summoned' type building.

Upgrades:
Ranged Attack upgrade: I need a good 3 icon set that's like magic...I'm thinking Magic Attack icon, Chaos Attack icon, and Fireball icon...

No one has any opinion? :(

apparently not
