Wow... just... WOW!
Finally, I found someone working with Earthbound stuff in A:M!
I am a huge Earthbound fan, I played Earthbound Zero, Earthbound, and I am almost finished with the Japanese version of Earthbound 2 (Mother 3) [it's actually easy to follow along with even though it's almost completely in Japanese.]
Anteways... Your Ness model is more realistic than the SSBM model, he almost actually looks like a real boy! That Titanic Ant model is actually pretty good too, considering you can only see a front view in the actual game.
I agree with the_black_mage about the lighting, although I don't think that's too big of an issue...
Maybe someday I will start an Earthbound project, but right now I'm too busy with playing music from the Earthbound series by ear. (I'm not kidding, I would play Earthbound music all DAY on the piano, that music is incredible!)
Anyways, great job!
