What I think the INMORTAL should be!

Inspired in the webcasts of the starcraft 2 replays, I looked at the inmortal an stalker, I don't see a reason to have diferent dragoon evolutions if its supossed that the darkones ant the sons fo aiur are fighting togheter against the zerg if they still be diferent factions its ok, but not agree with that even eith the inmortal model, the stalker at leas have a bit more of design work, but seriously a big cristal in a side a a weird crown over the mech?' isn't an anntena or it is? Maybe somone can help me to model this in 3d, even will be fun as fan vehicle in any mod game.

Let know your opinions and hope to se somene modeling this (it´s a WIP, I don't know how to paint sketches in the PC, so the colors are just for reference)
