Sorry for taking so long to review your work, I've been away and life's been busy.
The armored areas just look cluttered, You need to find ways to use the texture better as the way it's wrapped onto the mesh at the moment just looks randomly placed. Keeping the detail clear and simple will make it look much better in-game. Take a look at the Firelord, the metal parts are just armor plates and restraints, they tie the model together and support the fire-elemental areas which are what give the model character. Jigrael's guy had a metal helmet, probably because it'd be difficult to make a face out of lightning. You've got an opportunity here to use the natural features of the earth to make faces out of, go nuts with it!
The earth-y areas just don't stand out enough, particularly against the actual dirt terrain. It definitely needs more particles to jazz it up, dust and pebbles spring to mind. The glowy lights on the base as is just seem random; what do glowy lights have to do with the earth? If they're meant to represent lava, why not incorporate some molten areas on the model?
The shoulders stretch pretty badly in the death and dissipate animations. Also, you should change the event objects (under Node Manager in Magos) so that he doesn't bleed when he dies. The Bloodmage walk and stand animations seem really static and dull since he lacks the cape or legs of the BM. The arm movement fits really well, though. Maybe you might want to try basing it off the Lich instead?
This one just doesn't scream "earth elemental," you know? I see bits of the undead air barge with thick arms of mud. Think about some things you'd associate with the earth; immense weight and solidity, slow and powerful, dirt and dust, soil, rocks, crags, boulders and landslides... then work on how you'd incorporate it into your hero.
Compare your guy to the Firelord, notice just how much more
character the Firelord has?
