Thought to also put out a reference for Ota's own giant "mecha": Aperion
I actually worked on this before to work on the [url=]big picture of it with Ota[/url], and it ultimately paid off because the overall design is now more consistent compared to previous versions which might have looked ackward from certain angles or in certain poses.

Some unlisted info:
Aperion is not really a mecha but rather an inhert Living Vessel for a supernatural entity, which can only react in presence of the one who bonded with it, and while it can manipulate matter and space to turn any thought and wish of it's user(s) into reality, Aperion also features it's own weaponry based upon Ota's own ideal combat style and arsenal, at least for a giant mecha.
Also, it is one of those mechas that "hurt their user", as any damage taken is also felt by the pilot itself.
