Hello! And thank you, I’m glad you like that Bucky picture!
As for the machine, I used some screen shots from the movie itself (in bad quality, unfortunately, as there is only a low quality version out there) and some gifs found here on tumblr, but the only things that are more or less accurate with the machine form the movie, are the circle-like shape and the general shape of the piece that goes on his head (though, it actually goes over his eye, more on his face, I changed it a bit for artistic reasons 8D). But the details are all made up, I just keep adding to the general shape some random-machine-parts-that-look-good. Also I added all those wires because, yeah, they look good. They remind me of either ribbons or some bizarre tentacles, and I like that a little bit disturbing feeling. I may have been inspired by Msamune Shirow’s “Ghost in the Shell”, because, yeah, cyborgs ♥
So, for the actual good references we will have to wait for the Blu-ray release 8D
