This is indeed a very nice model, I'm actually impressed about the texture, it definitely looks like wow-ish and I must say that for a while I first thought it was done by Blizzard, I really am impressed at this. I hope that everything goes well and that the animation will be succesfull
Although if I may add an addition, I don't know if this was already planned but are you guys also making the engine move like it shakes? Although if that is included, I don't know how you're able to make it sound like the engine is loading, unless there's a soundfile played while you are standing still on your mount, then you just swap that soundfile with a engine soundfile.
