15mm Sci Fi Light Mech Scale Comparison

I have assembled and under coated the three 28mm Copplestone power armour figures that I'm using as light walkers or mechs for my 15mm sci-fi project, very much in a Heavy Gear style. I thought I'd take a couple of comparative photos alongside the 15mm figures and vehicles to see how they matched up in terms of design and scale. I think they look spot on and, when I have a whole squad assembled, will complement the GZG 'cyclops' helmet figures and Gauntlet hover APC's really well.
