Lord Archon Alino Las'Kalo model help -showcase model, not game play one-

Alright, I want to do a model of myself, as a showcase one, some of you may be familiar with my army, some may not. Same with my fluff

anyways, what I was wanting to do was use a Monstrous Creature sized base, and have Archon Las'Kalo fighting Archon Lamixill atop of a mix of dead Kabalites from the Darkened Light and the Poisoned Dart. -Probably a box of 10 guys on the base, I'll green stuff the ground up I think to make it look like more bodies-

anyways, I was curious as to how I should go about doing this. That's all, any advice on how I should get started? Because I want this to be the nicest looking piece I have ever done.

I was wanting Las'Kalo to have both his huskblades out while fighting Lamixell, and both his blast pistols sheathed.

Lamixell would be slashing at Las'Kalo with his Agoniser and it would be trying to wrap around his neck, and have his double-bladed venom blade slashing at one of Las'Kalo's arms.
