I kind of figured that, it just surprises me that the studio prop and cgi guys didn't make a more sound design - as most newer big budget sci-fi productions usually use pretty believable content, in dealing with working models anyway.
I didn't realize the toy was such high quality though, I mean it actually looks like precision machined metal parts - so thanks for that!
BTW, did you happen to do the LCD screen with his face on it? And the animations for it too? That would be even more awesome than your model already is!
