You stole the damn alien. Admit it, remove it from the page, and I'm happy. The rest probably are your own, but the alien isn't. Stop trying to prove you didn't do it, since you're only digging yourself in deeper. You've been proved wrong once in that other thread, stop trying to say you didn't steal it.

Be a man, remove it, apologise, then go about your modeling.
