all i can say is wow nice job.

theres a few things that are off like the other poster said but it looks like you can make them with no problem

According to the Stand Alone Complex:
You have forgot one more eye in the bottom of the abdomen. Something like it is only on the side view and it isn't white and that big. The design of hands is actually a bit different too, and the main weapon between them is missing, but still - great work!
