So had a quick look at bot mode. Was easy enough to attach Dino neck and chest spikes, checked out the neck (will definitely need to loosen screw) very tight to turn neck. Managed to open head and gave eyes a quick coat with the red gundam marker I have ( looks a bit better).
Articulation is okay, no rachets at all though? knees are a bit loose (don't see any way to tighten) and the feet/ankles are not great but I can get some poses from it.
