Giving Lockdown some needed height - the Studio Series are fine but to me are a smidge too small compared to TF5 voyager Optimus (my current preferred mold).

ROTF Lockdown sized up well - deluxe-sized car to a voyager-sized robot! - but the head was based on the animation version.

Luckily the AoE Lockdown head fitted on the ROTF mold (albeit his head does look downwards). Dremelled off the spikey bits and repainted, with a black wash afterwards.

I've thought about removing the supercharger and filling the gap in on the bonnet... maybe later.
