The frame(the gray frame, not the psychoframe) is a noticeably lighter shade of gray and is less metallic, and looks more plastic-y to me. This is probably one of the must have models. I'd say the difficulty is 4/5 but the end results are 5 stars! Additionally, the Ver Ka comes with pink beam sabres instead of the OVA's clear blue, and there are some colour differences on the frame, blue feet parts, and weapons. This thing has the hardest decals ever, but its not impossible.
