NeoChaos said: No, because there doesn't seem to be a reference to the movie on the Pixiv page.
Now there is a tag in Pixiv with the movie name on it... But the robot, despite being similar in style, doesn't look like any of the ones from the film. Probably the artist saw early images of the movie and created his own original model. Still, the ghost-fighting control type is identical to the one used by one character in the film, so it must be both original and inspired art.

It's also identical to teleroboxer on the virtual boy from 1995. Also G Gundam.
The whole robots being controlled by full body motion is not new or unique.
