This
ROTF demolisher is also based on the concept art.
Did a few mods:
1. added some additional details on the main body using Pla-plates and photoetched parts.
2. Added claws at the scoop. (I still prefer JinSaotome's claws, but I don't own soundwave).
3. Scratched built additional pistons.
4.Additional detailing and mechanism under the chest and inner frame which look hollow initially.
Almost done, just waiting for the paint to dry, before doing the finishing touches.
